New phenyl and phenylthienyl derivatives end-functionalized with carbazole and a-carboline, 9-(4(9-H-carbazol-9-yl)phenyl)-9H-carbazole, 9-(4-(9H-carbazol-9-yl)phenyl)-9H-pyrido[2,3-b]indole, 9(3-(9H-carbazol-9-yl)pheny1)-9H-carbazole, 9-(3-(9H-carbazol-9-yl)pheny1)-9H-pyrido[2,3-b]indole, 9-(4-(5-(9H-carbazol-9-yl)thiophen-2-yl)phenyl)-9H-carbazole, and 9-(3-(5-(9H-carbazol-9-yl) thiophen-2-yl)phenyl)-9H-carbazole were synthesized and characterized as organic semiconductors for organic thin-film transistors (OTFTs). Most compounds exhibited p-channel characteristics with carrier mobility as high as 1.7 x 10(-5) cm(2)Ns and a current on/off ratio of 10(2)-10(4) for top-contact/bottom-gate OTFT devices.
