A new blue-light emitting polymer that alternates between fluorene and alkoxynaphthalene structure has been developed. The fluorene and naphthalene units were highly distorted with an angle of 76.22° according to theoretical calculations. The obtained polymer has a weight average molecular weight of 273,800 with a polydispersity index of 2.35, good solubility and high thermal stability with a T ...
A blue electroluminescent polymer, random copolymer of fluorenylstilbene and fluorene, was prepared by the nickel catalyzed coupling reaction. The structure and properties of the copolymer were analyzed by various spectroscopic methods. The obtained polymer had good solubility and thermal stability with high T g . The polymer in thin film emits strong blue luminance (max=468nm) with narrow...
New poly(terphenylenevinylene) derivative with an alkoxy group and an electron withdrawing cyano group, poly(1,4-phenylene-2′-methoxy-5′-ethylhexyl-1′,4′-phenylene-1″,4″-phenylene-α-cyanovinylene), was synthesized via the Suzuki coupling reaction. The polymer was completely soluble in common organic solvent and showed good thermal stability up to 380°C. The presence of the electron withdrawing cyano...
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 phenyl pendant group in a vinyl bridge showed blue shifted absorption spectra, large band gap and enhanced thermal stability...
