Abstract
In this study, we report on material design of light-emitting organic field effect transistors (LE-OFETs). Some of newly synthesized pyrene and bis-styryl derivatives as an active layer demonstrated high field effect mobility (μh == 0.11 cm2/Vs, C 6-BSBP) and high photoluminescence efficiency (φPL-80%, symmetrical di-substituted pyrene derivatives). Further, external electroluminescence quantum efficiency was improved from 0.01% in TPPy to 0.15-0.54% in pyrene dimmers. In addition, we demonstrate an increase of EL efficiency by introducing guest-host system and ambipolar operation mechanism.
