摘要
Perfluoro-1,3,5-tris(p-quaterphenyl)benzene (PF-13Y) and perfluoro-1,3,5-tris(p-quinquephenyl)benzene (PF-16Y) have been synthesized and characterized. They showed higher glass transition temperatures compared with perfluoro-1,3,5-tris(p-terphenyl)benzene (PF-10Y). Organic light-emitting diodes were fabricated using these materials as the electron-transport layers. PF-13Y and -16Y are better electron transporters than PF-10Y. The electron mobilities of PF-10Y and Alq(3) were measured by the time-of-flight technique. PF-10Y showed higher electron mobilities (10(-4)cm(2)/V s) and weaker electric field dependence compared with Alq(3).) (C) 2002 Elsevier Science (USA).
