Bithiazole-based poly(arylenevinylene) is synthesized via the Co-catalyzed hydroarylation polyaddition of N,N,N',N'-tetrahexyl-(2,2'-bithiazole)-4,4'-dicarboxamide with 2,7-diethynyl-9,9-bis(2-ethylhexyl)fluorene in a regioselective manner. The introduction 2,2'-bithiazole unit deepens highest occupied molecular orbital (HOMO) and lowest unoccupied (LUMO) energy levels polymer compared to analogous bithiophene-based poly(arylenevinylene). N-Methylation N-oxidation thiazole moiety further deepen HOMO LUMO polymer, which attributed enhanced electron-withdrawing effect. N-oxidized exhibits high photoluminescence quantum yield serves as an emitting material organic light-emitting diode, its deep level efficiently restrains trapping holes host poly(vinylcarbazole) matrix.
