On July 13, 2004, Cho, Nam Sung; Hwang, Do-Hoon; Jung, Byung-Jun; Lim, Eunhee; Lee, Jaemin; Shim, Hong-Ku published an article.Computed Properties of 146370-51-6 The title of the article was Synthesis, characterization, and electroluminescence of new conjugated polyfluorene derivatives containing various dyes as comonomers. And the article contained the following:

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. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Computed Properties of 146370-51-6

Shankar, Jaya Seeli; Kumar, Sangeetha Ashok; Periyasami, Bhuvana K.; Nayak, Sanjay K. published an article in 2020, the title of the article was Mechanism of photoinduced charge transfer at MEH-PPV and titanium dioxide nanoparticle interface.Recommanded Product: 1-((2-Ethylhexyl)oxy)-4-methoxybenzene And the article contains the following content:

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. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Recommanded Product: 1-((2-Ethylhexyl)oxy)-4-methoxybenzene

And the article contained the following:

The blue electroluminescent polymers, poly(terphenylenevinylene) derivatives that have advantages of PPP and PPV, were prepared by Suzuki coupling reaction. The structure and properties of the polymers were analyzed by various spectroscopic methods. Poly(MHTPPV) and poly(TPPV) with Ph pendant group in a vinyl bridge showed blue shifted absorption spectra, large band gap and enhanced thermal stability as compared with that of poly(MHTPV). The PL spectra of the films of the polymers showed maximum peaks at 450-460 nm, which are pure blue emissions. The blue electroluminescence (λmax=450-460 nm) was obtained with the turn on voltage of 8-10 V, when the simple light-emitting diodes of ITO/polymer/Al were fabricated. The excimer emission due to interchain interaction was reduced by the introduction of substituents into the vinyl bridge and (or) the main chain.
