Wang, Hui published the artcileSynthesis and characterization of poly(N-arylcarbazole-alt-aniline) copolymers as blue-emitting host matrix for polymer light-emitting diodes, Quality Control of 946491-48-1, the publication is Molecular Crystals and Liquid Crystals (2006), 95-107, database is CAplus.
Thermally stable and solution-processable poly(N-arylcarbazole-alt-aniline) copolymers with high structural integrity were synthesized in good yields via palladium-catalyzed polycondensation of aniline with corresponding N-arylcarbazole monomers such as N-(2-ethylhexyloxyphenyl)-3,6-dibromocarbazole, bis[6-bromo-N-(2-ethylhexyloxyphenyl)carbazole-3-yl] and N-(4-(2-ethylhexyl)-3,5-dibromomethylene-phenyl)carbazole, resp. The optical and electrochem. properties of these copolymers were measured and compared with those of poly(N-alkylcarbazole-alt-aniline) copolymer. All synthesized poly(N-arylcarbazole-alt-aniline) copolymers showed maximum UV-Vis absorption peaks at around 300 nm in THF solution, and exhibited maximum photoluminescence peaks in the blue emission range from 430 to 460 nm. Poly(N-arylcarbazole-alt-aniline) copolymers had a wider band gap energy than poly(N-alkylcarbazole-alt-aniline) copolymers.
