Wang, Hui published the artcileGreen and Red Electrophosphorescent Devices Consisting of Cabazole/Triarylamine-Based Polymers Doped with Iridium Complexes, Related Products of bromides-buliding-blocks, the publication is Molecular Crystals and Liquid Crystals (2007), 279-291, database is CAplus.

Two types of polymers were synthesized such as poly[N-(2-ethylhexyl)carbazole-alt-N-(4-aminophenyl)carbazole] (PECAC) and poly[N-(2-ethylhexyloxy-phenyl) carbazole-alt-N-(4-aminophenyl)carbazole] (PEPCAC). These polymers are designed to have carbazole groups with wide band gap and a triarylamine moiety with a hole transporting property. Green and red phosphorescent polymer light emitting diodes (PhPLEDs) were fabricated with an emitting layer consisting of either PECAC or PEPCAC as a host matrix with suitable iridium complexed, Ir(ppy)₃ as a green or IR-PIQCH as a red dopant, resp. Red PhPLEDs doped with IR-PIQCH exhibited maximum EL emission peaks at 620 nm with higher luminescence and lower driving voltage, due to effective energy transfer from host polymers to IR-PIQCH red dopant. Based on HOMO and LUMO levels of the polymers and Ir(ppy)₃, however, the synthesized polymers could not be served as suitable host polymers for Ir(ppy)₃ green dopant. Ir(ppy)₃ doped PhPLEDs exhibited red shift and wide range of EL emission.

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.
