| 英文摘要 | A series of novel branched polythiophene derivatives bearing different densities of vinylene-bridges as linking chains were synthesized by a general synthetic strategy. the organic field-effect transistors, which were fabricated by spincoating the polymer solutions onto octadecyltrichlorosilane-modified sio(2)/si substrates with top-contact configuration, afforded a high mobility of 8.0 x 10(-3) cm(2) v(-1) s(-1) with an on/off ratio greater than 10(4) and a threshold voltage of about -3 v in saturation regime. the devices based on these polymers possessed better performance than those of polymers without conjugated bridges and polymers with longer conjugated bridges. these results demonstrated that the combination of conjugated polythiophene backbones and vinylene-bridges would improve the carrier mobility. as an emerging class of conjugated materials, polymers with vinylene-bridges as linking chains would open up new opportunities in organic electronics, and their applications in organic electronics are promising.
