Abstract
Abstract 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 .
