Fully soluble poly[2-(2-ethylhexyloxy)-5-methoxy-p-phenylenevinylene] was synthesized by the polymerization of 2-(2-ethylhexyloxy)-5-methoxy-1,4-xylylene dibromide with addition of mol. weight modifiers (chain stopper, free radical scavengers) to a polymerization system containing monomer, catalyst, and solvent. The polymers synthesized in this work were characterized by IR, NMR, and UV-visible spectroscopy, and gel-permeation chromatog. Results show that the weight-average mol. weight of the polymer can be controlled by the addition of chain stopper (benzyl bromide) and radical inhibitor (BHT). The polymerization mechanism in the presence of these additives was also discussed. A dual mechanism involving carbene for the polymerization was proposed.

Lee, Chang-Soo published the artcileA novel fluorescent nanoparticle composed of fluorene copolymer core and silica shell with enhanced photostability, Name: 1-((2-Ethylhexyl)oxy)-4-methoxybenzene, the publication is Colloids and Surfaces, B: Biointerfaces (2012), 219-225, database is CAplus and MEDLINE.

A variety of fluorescent nanoparticles have been developed for demanding applications such as optical biosensing and fluorescence imaging in live cells. Silica-based fluorescent nanoparticles offer diverse advantages for biol. applications. For example, they can be used as labeling probes due to their low toxicity, high sensitivity, resolution, and stability. In this research, a new class of highly fluorescent, efficient nanoparticles composed of a newly synthesized poly[di(2-methoxy-5-(2-ethylhexyloxy))-2,7-(9,9-dioctyl-9H-fluorene)] (PDDF) core and a silica shell (designated as PDDF@SiO₂) were prepared using a simple reverse micelle method, and their fluorescent properties were evaluated using methods such as single-dot photoluminescence measurements. The enhanced photostability of the particles and their potential applications for bioanal. are discussed in this article. The morphol., size, and fluorescent properties for prepared PDDF@SiO₂ nanoparticles were characterized using transmission electron microscopy (TEM), SEM (SEM) and photoluminescence spectroscopy. The prepared particles size, which was approx. 60 nm, resulted in an excellent colloidal stability in a physiol. environment. The photobleaching dynamics, total numbers of emitted photons (TNEP) and statistical measurements of individual nanoparticles were observed using laser scanning fluorescence microscopy to assess the structure and photostability of PDDF@SiO₂ nanoparticles. Addnl., PDDF@SiO₂ nanoparticles were used in cell toxicity and permeation tests for biol. analyses, demonstrating a great potential for use as powerful, novel materials within the emerging fields of biosensing and biomedical engineering.

Shih, Kuo Sheng published the artcilePhotoluminescence of MEH-PPV Brushes, Pancakes, and Free Molecules in Solutions and Dry States, COA of Formula: C15H24O2, the publication is ACS Photonics (2015), 2(1), 33-42, database is CAplus.

Photoluminescence (PL) of a conjugated polymer MEH-PPV, poly[2-methoxy-5-(2′-ethylhexyloxy)-1,4-phenylenevinylene], grafted on a silicon wafer with controlled tether spacing was studied to reveal the effects of mol. conformation, chain packing, and mech. stress. In the solvent-swollen state, the PL of the densely grafted polymer (denoted “brushes”) was blue-shifted substantially relative to the lightly grafted (denoted “pancakes”) and free polymers. As solvent evaporated, while for the brushes the changes in PL were insignificant, the PL spectra of the pancakes underwent large blue shifts and exhibited significant efficiency enhancements up to ∼175-fold. The solvent evaporation effects were attributed to mol. deformations resulting from coil contraction on the substrate, which gave rise to conjugation-disruptive kinks (blue shift) and segmental stretching (PL enhancement) in the dried mols. Moreover, heterojunctional quenching was found significantly suppressed by the mech. stresses. Similar behavior was observed in dried free single mols. These results unveil the fundamental role of mech. stresses, not only indirectly through their influence on mol. conformations, but directly via alterations of the excitonic behavior.

The synthesis and the chem. phys. characterization of new photoluminescent (PL) chromophores and polymers are reported. Chromophores (oligo-PPV sym. derivatives ending with amino groups) are strong blue emitters with a PL quantum yield of ∼70% in dioxane solution They have been used to prepare polyamides by reaction with aliphatic acyl dichlorides in which emitting and non emitting units are alternated. PL properties of the synthesized polyamides have been evaluated in solution and reveal a strong blue emission (PL quantum yield ∼60%), to increase the solubility of these systems, oligomers have been purposely prepared and then characterized. They show a peculiar white emission when excited in DMF solution; to get insight into this interesting behavior, asym. monoacetylated chromophores have been prepared as model compounds for the chromophoric end groups of the polyamide chains. The emission spectra of these compounds reveal a broad excimeric yellow emission which is responsible, along with the blue emission of the inner chromophoric units, of the overall white emission of the oligomers. © 2009 Wiley Periodicals, Inc.

Makkad, Sarabjot Kaur published the artcileπ-Conjugated Chromophore Incorporated Polystyrene Nanobeads as Single Optical Agent for Three-Channel Fluorescent Probe in Bioimaging Application, Synthetic Route of 146370-51-6, the publication is ACS Biomaterials Science & Engineering (2017), 3(8), 1788-1798, database is CAplus and MEDLINE.

Fluorescent polystyrene (PS) nanobeads in the size range ∼70-120 nm incorporating perylene bisimide (PBI-PS) and/or oligo(p-phenylenevinylene) (OPV-PS) were developed by the miniemulsion polymerization technique. A dye loading content (DLC) of <3% was sufficient to impart high fluorescence emission capability to the PS beads. OPV-PS exhibited emission in the range 400-550 nm with peak emission at 450 nm (λ_ex = 350 nm; φ_FL = 26%); PBI-PS showed emission from 520-650 nm with peak emission at 545 nm (λ_ex = 490 nm; φ_FL = 9.7%) in 1× PBS buffer, whereas OPV(PBI)-PS nanobeads incorporating both the fluorophores exhibited multicolor emission capabilities (λ_ex from 350 to 490 nm). The nanoparticles were characterized by field-emission SEM (FESEM), TEM and dynamic light scattering (DLS) for size and zeta potential for surface charge. For bioimaging applications, the PS nanoparticles were incubated with HeLa cells. Cell viability anal. involving HeLa cells showed >90% cell viability confirming the biocompatibility of the PS beads. The cellular uptake of the nanoparticles was confirmed by flow cytometry anal. and confocal laser scanning microscopy (CLSM) images. The subcellular localization of the nanoparticles in the cytoplasm could be precisely established by their simultaneous multicolor emission. The PS-based single optical agent presented here that can function as three-channel fluorescent probe to meet the requirements for multicolor bioimaging is advantageous.

The present work endeavors towards the scientific study on influence of ZnO nanoparticles on the optical characteristics of Poly [2 Methoxy (5, 2′ Ethylhexyloxy)-P-Phenylenevinylene] (MEH-PPV), a light emitting polymer. Hybrid nanocomposites of MEH-PPV were prepared by dispersing ZnO nanorods at loading concentrations of 1 weight % and 3 weight %. The structural characteristics of the hybrid composites were investigated using FTIR spectroscopy and X-ray diffraction. The UV absorption spectra and Photoluminescence emission spectra were analyzed in order to study the optical characteristics of nanocomposite. The optical constants were determined and the suitability of the composites for light emission was analyzed. The incorporation of ZnO nanorods facilitates the shift in emission wavelength and witnesses the color tuning ability and multicolor emission from the composite.

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 (λ_max=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.

Treatment of the complex trans-[Pt(Ph)(Cl)(Et₃P)₂] with half equivalent of the diterminal alkynes 1b–4b in ⁱPr₂NH-CH₂Cl₂, in the presence of CuI, at room temperature, afforded the platinum(ii) di-yne complexes trans-[(Et₃P)₂(Ph)Pt-CC-R-CC-Pt(Ph)(Et₃P)₂] [R = 1-(2-ethylhexyloxy)-4-methoxybenzene-2,5-diyl 1c, quinoline-5,8-diyl 2c, 2,3-diphenylquinoxaline-5,8-diyl 3c, 2,1,3-benzothiadiazole-4,7-diyl 4c] in good yields. The new acetylide-functionalized ligands and the platinum(ii) σ-acetylide complexes have been characterized by anal. and spectroscopic methods and x-ray single crystal structure determinations for 2c–4c. The absorption spectra of the complexes 2c–4c show substantial donor-acceptor interaction between the platinum(ii) centers and the conjugated ligands. The photoluminescence spectra of 1c–3c show characteristic singlet (S₁) and triplet (T₁) emissions. Both the singlet and triplet emissions as well as the absorption decrease in energy with increasing electronegativity of the spacer groups along the series 1c–4c.
