Two novel poly(1,4-phenylenevinylene) (PPV) derivatives containing liquid crystalline oxadiazole side chains were prepared by a dehydrochlorination process. The homopolymer poly[2-methoxy-5-((2-methoxy-phenyl)-5-hexyloxy-phenyloxy-1,3,4-oxadiazole)-1,4-phenylenevinylene] (HO-PE₆) is insoluble in common solvents, whereas the copolymer poly[2-methoxy-5-((2-methoxy-phenyl)-5-hexyloxy-phenyloxy-1,3,4-oxadiazole)-(2-methoxy-5-(2′-ethylhexyloxy))-1,4-phenylenevinylene] (CO-PE₆) is soluble in common solvents such as chloroform, THF, and p-xylene. The mol. structure of CO-PE₆ was confirmed by FTIR, ¹H-NMR, UV-vis spectroscopy, and polarized light microscopy. CO-PE₆ showed a maximum emission at 556 nm in chloroform and at 564 nm in solid film, when excited at 450 nm. The maximum electroluminescence emission of the device indium-tin oxide (ITO)CO-PE₆/Al is at 555 nm. The turn-on voltage of LEDs based on CO-PE₆ and MEH-PPV is 6.5 and 8.5 V, resp. The electron mobility of CO-PE₆ is higher than that of MEH-PPV based on the results of current-voltage and electrochem. behavior of both MEH-PPV and CO-PE₆.

Zhang, Su-Yang published the artcileSynthesis, characterization, and electro-optical properties of a soluble conjugated polymer containing an oxadiazole unit in the main chain, Name: 1-((2-Ethylhexyl)oxy)-4-methoxybenzene, the publication is Journal of Applied Polymer Science (2003), 89(10), 2618-2623, database is CAplus.

A novel copolymer, poly{[2,5-di-phenylene-1,3,4-oxadiazole-vinylene]-[2-methoxy-5-(2-ethylhexyl-oxy)-1,4-phenylenevinylene]}(MEH-OPPV) containing a high-electron-affinity unit of aromatic oxadiazole in the main chain is synthesized through the Wittig condensation reaction. The obtained copolymer is easily soluble in conventional organic solvents. The structure of the copolymer was characterized by Fourier transform IR, ¹H NMR, thermogravimetric anal. (TGA), differential scanning calorimetry (DSC), and UV-visible and photoluminescence spectroscopy. The TGA result indicates that the copolymer has very high thermal stability (stable up to 310°C in nitrogen), while DSC investigation demonstrates that the glass transition temperature (T_s) is 143°C, which might be a merit for the long-life operation of light-emitting devices. The absorption spectrum of film sample of the copolymer reveals two peaks at 310 and 370 nm, resp., and the edge absorption corresponds to a band gap of 2.46 eV. A single-layer light-emitting diode device ITO/MEH-OPPV/Al is successfully fabricated. The device emits visible yellowish-green light above the bias voltage of 4.0 V under ambient condition.

Shankar, Jaya Seeli published the artcileMechanism of photoinduced charge transfer at MEH-PPV and titanium dioxide nanoparticle interface, Application of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene, the publication is Indian Journal of Chemistry, Section A: Inorganic, Bio-inorganic, Physical, Theoretical & Analytical Chemistry (2020), 59A(9Spec.Iss.), 1278-1284, database is CAplus.

In this study, we investigated mechanisms of photoinduced electron transfer from a conjugated polymer poly(2-methoxy-5-(2-ethylhexyloxy)1,4-phenylenevinylene) (MEH-PPV) to titanium dioxide (TiO₂) nanoparticles (acceptor) through steady-state photoluminescence (PL) spectroscopy. Since mixed phase TiO₂ has better photocatalytic compared to single phase, it is an efficient charge separation process during photoexcitation of polymer nanocomposites by incorporating the mixed phase TiO₂ nanoparticles into the MEH-PPV polymer matrix through in situ polymerization Structural characterization revealed only phys. interaction between the polymer matrix and dispersed nanoparticles. The absorbance spectra of nanocomposites also indicated the absence of ground state complex formation. Luminescence quenching of polymer nanocomposites compared to pristine MEH-PVV signifies the charge transfer taking place at the MEH-PPV/TiO₂ interfaces. Thus, the MEH-PPV/ mixed phase TiO₂ nanocomposite serves as an active layer for photovoltaic application.

Amrutha, S. R. published the artcileControl of π-Stacking for Highly Emissive Poly(p-phenylenevinylene)s: Synthesis and Photoluminescence of New Tricyclodecane Substituted Bulky Poly(p-phenylenevinylene)s and Its Copolymers, Application In Synthesis of 146370-51-6, the publication is Journal of Physical Chemistry B (2006), 110(9), 4083-4091, database is CAplus and MEDLINE.

In the present work, we have demonstrated a facile approach to increase the luminescence of the poly (p-phenylenevinylene)s via controlling the mol. aggregates induced by π-stacking. We have synthesized new bulky tricyclodecane (TCD) substituted PPVs: poly(2-methoxy-5-tricyclodecanemethyleneoxy-1,4-phenylenevinylene) (MTCD-PPV), poly(bis-2,5-tricyclodecanemethyleneoxy-1,4-phenylenevinylene) (BTCD-PPV), and a series of sym. substituted bulky PPV copolymers (P-1-P-7) covering the entire composition range from 0 to 100 mol %. The structures of the monomers and polymers were confirmed by ¹H NMR and FTIR, and the mol. weights were determined by gel permeation chromatog. The composition anal. by NMR revealed that the bulky monomer was highly reactive and the incorporation of bulky units in MEH-PPV increased irresp. of the feed ratio. The polymers possess good solubility, high mol. weights, good thermal stability, and so forth. The mol. weights of the PPV copolymers were also significantly affected by the bulky substitution: the higher the incorporation of bulky units, the lower the mol. weight The absorption and emission studies revealed that there was no influence on the MEH-PPV by TCD substitution in solution whereas in the solid state the photoluminescence intensity of PPV increased more than 10 times. The luminescence increase in PPV was observed throughout the entire bulk and was not confined to any particular domain in the polymer. The bulky PPV copolymers showed that both the luminescence intensity (in film) and quantum yields (in solution) increased with an increase in the extent of BTCD incorporation in the MEH-PPV and attained a maximum for 50% BTCD. The TCD unit has thus proved to be an efficient bulky susbstituent for PPV as it controls the π-stack-induced mol. aggregates in the polymer chains by increasing the interchain distances. The new bulky PPV copolymers are highly soluble, thermally stable, and highly luminescent besides being economically cheap compared to the other materials reported so far for the bulkier approach in π-conjugated materials.

Deepa, P. published the artcilePolyurethane-oligo(phenylenevinylene) random copolymers: π-conjugated pores, vesicles, and nanospheres via solvent-induced self-organization, Name: 1-((2-Ethylhexyl)oxy)-4-methoxybenzene, the publication is Journal of Polymer Science, Part A: Polymer Chemistry (2008), 46(17), 5897-5915, database is CAplus.

We report a new series of polyurethane-oligo(phenylenevinylene) (OPV) random copolymers and their self-assembled nanomaterials such as pores, vesicles, and luminescent spheres. The polymers were synthesized through melt transurethane process by reacting a hydroxyl-functionalized OPV with diurethane monomer and diol under solvent-free and nonisocyanate conditions. The amount of OPV was varied up to 50 mol % in the feed to incorporate various amounts of π-conjugated segments in the polyurethane backbone. The π-conjugated segmented polymers were subjected to solvent induced self-organization in THF or THF+water to produce variety of morphologies ranging from pores (500 nm to 1 μm) to spheres (100 nm to 2 μm). Upon shining 370-nm light, the dark solid nanospheres of the copolymers transformed into blue luminescent nanoballs under fluorescence microscope. The mechanistic aspects of the self-organization process were studied using solution FTIR and photophys. techniques such as absorption and emission to trace the factors which control the morphol. FTIR studies revealed that the hydrogen bonding plays a significant role in the copolymers with lower amount of OPV units. Time resolved fluorescent decay measurements of copolymers revealed that mol. aggregation via π-conjugated segments play a major role in the samples with higher OPV content in the random block polymers.

Electroluminescent copolymers with fluoro groups on vinylene units, poly(2-ethylhexyloxy-5-methoxy-p-phenylenevinylene-co-2-dimethyloctylsilyl-p-phenylenedifluorovinylene) (MEH-PPV-co-DMOS-PPDFV) and poly(2-dimethyloctylsilyl-p-phenylenevinylene-co-2-dimethyloctylsilyl-p-phenylenedifluorovinylene) (DMOS-PPV-co-DMOS-PPDFV), were synthesized by the Gilch polymerization route. The fluoro groups were introduced on vinylene units to increase the electron affinity of the copolymers. In both copolymers, the band gap increased with higher ratio of DMOS-PPDFV. As compared to the photoluminescence (PL) spectra in solution, the PL spectra in solid state and EL spectra of both copolymers showed red shift and broad peaks caused by aggregation. The LEDs fabricated using MEH-PPV-co-DMOS-PPDFVs emit light with maximum at around 538-577 nm. By adjusting the feed ratio of DMOS-PPDFV in the copolymer, the emission colors were tuned from orange yellow to green. The DMOS-PPV-co-DMOS-PPDFV showed maximum electroluminescence (EL) peaks at about 514-543 nm. The DMOS-PPV-co-DMOS-PPDFV with 1:9 feed ratio showed the highest luminescence efficiency of 1.31 lm/W.

Ahn, Taek published the artcileBlue Electroluminescent Polymers: Control of Conjugation Length by Kink Linkages and Substituents in the Poly(p-phenylenevinylene)-Related Copolymers, Synthetic Route of 146370-51-6, the publication is Macromolecules (1999), 32(10), 3279-3285, database is CAplus.

Poly[o(m,p)-phenylenevinylene-alt-2-methoxy-5-(2-ethylhexyloxy)-p-phenylenevinylene], o(m,p)-PMEH-PPV, and poly[o(m,p)-phenylenevinylene-alt-2,5-bis(trimethylsilyl)-p-phenylenevinylene], o(m,p)-PBTMS-PPV, of varying effective conjugation lengths were synthesized by the well-known Wittig condensation polymerization between the appropriate diphosphonium salts and the dialdehyde monomers such as terephthaldicarboxaldehyde, isophthalaldehyde, and phthalic dicarboxaldehyde. The conjugation lengths of the polymers were controlled by substituents and kink (ortho and meta) linkages. The resulting polymers were highly soluble in common organic solvents. The synthesized polymers showed UV-visible absorbance and photoluminescence (PL) in the ranges of 330-430 nm and 440-550 nm, resp. The maximum emission peak of p-PMEH-PPV was blue shifted about 30 nm compared to that of MEH-PPV, which is due to an unsubstituted phenylene unit. In addition, o-PMEH-PPV and m-PMEH-PPV showed PL emission maximum peaks at 500 and 490 nm, resp., because ortho and meta linkage of the o(m)-PMEH-PPV reduced π-conjugation lengths. The trimethylsilyl substituent has no electron donating effect; therefore, the PL maximum of p-PBTMS-PPV was far more blue shifted (to 485 nm). Consequently, maximum PL wavelengths for o-PBTMS-PPV and m-PBTMS-PPV appeared around 470 and 440 nm, resp. A single-layer light-emitting diode device was fabricated which has a simple ITO (indium-tin oxide)/polymer/Al configuration. The threshold bias of trimethylsilyl-substituted o(m,p)-PBTMS-PPV was in the range of 8-9 V. As in the photoluminescence spectra, the dramatic change of emission color was also shown in electroluminescence spectra of p-PMEH-PPV, p-PBTMS-PPV, and o-PBTMS-PPV when the operating voltage was about 8-9 V.

Cho, Nam Sung published the artcileSynthesis, characterization, and electroluminescence of new conjugated polyfluorene derivatives containing various dyes as comonomers, Name: 1-((2-Ethylhexyl)oxy)-4-methoxybenzene, the publication is Macromolecules (2004), 37(14), 5265-5273, database is CAplus.

Four new fluorene-based alternating polymers (PFR1-S, PFR2-S, PFR3-S, and PFR4-S) containing different comonomers, i.e., 2,5-bis{2-(4′-bromophenyl)-1-cyanovinyl}-2-(2′-ethylhexyloxy)-5-methoxybenzene (R1), 2,5-bis{2-(4′-bromophenyl)-2-cyanovinyl}-2-(2′-ethylhexyloxy)-5-methoxybenzene (R2), 2,5-bis{2-(4′-bromothienyl)-1-cyanovinyl}-2-(2′-ethylhexyloxy)-5-methoxybenzene (R3), and 2,5-bis{2-(4′-bromothienyl)-2-cyanovinyl}-2-(2′-ethylhexyloxy)-5-methoxybenzene (R4), were designed, synthesized, and characterized. These polymers were thermally stable and readily soluble in common organic solvents. Single layer LED devices fabricated from these polymers emitted bluish green to pure red light. The color of the light emitted by the homopolymer, poly(9,9-dioctylfluorene-2,7-diyl) (PDOF), can be tuned by incorporating R1, R2, R3, and R4 comonomers, which have narrower band gaps. The absorption and emission maxima of the copolymers varied according to the position of the cyano group in the vinylene unit (α- or β-position) and the type of incorporated aromatic group (thiophene or phenylene). Notably, PFR4-S, prepared from R4 and 2,7-bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-9,9′-dioctylfluorene, showed pure red emission (CIE coordinate values x, y = 0.66 and 0.33, resp.) that is almost identical to the standard red (0.66, 0.34) demanded by the National Television System Committee. PFR3-S also exhibited pure red emission (chromaticity values x, y = 0.63 and 0.38, resp.), and its maximum luminance and maximum external quantum efficiency were approx. 3100 cd/m² at 6 V and 0.46% at 4 V, resp.
