The preparation of triarylamine N-functionalized 3,6-linked carbazole homopolymers as well as alternating copolymers with 2,5-diphenyl-[1,3,4]oxadiazole and benzo[1,2,5]thiadiazole was undertaken using Suzuki cross-coupling polymerization procedures associating 3,6-bis(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-9-(bis[4(2-butyl-o ctyloxy)-phenyl]-amino-phen-4-yl)-carbazole and, respectively, 3,6-dibromo-9(bis[4-(2-butyl-octyloxy)-phenyl]-amino-phen-4-yl)-carbazol e, 2,5-bis(4-bromo-phenyl)-[1, 3,41oxadiazole, and 4,7-dibromo-benzo[1,2,5]thiadiazole. Both the carbazole homopolymer and alternating copolymer with 2,5-diphenyl-[1,3,4]oxadiazole were found as wide-band gap materials emitting in the blue part of the electromagnetic spectrum while the carbazole alternating copolymer with 4,7-benzo[1,2,5]thiadiazole had a narrower band gap and emitted in the orange part of the electromagnetic spectrum. The new polymers are thermally stable up to 300 degrees C. A discussion of the electrochemical and optical properties of the new polymers is presented. (c) 2007 Wiley Periodicals, Inc.
