碩士 === 國立中央大學 === 化學研究所 === 95 === In this study, we have sucessfully synthesized a series of compound
containing benzimidazole and/or arylamine moieties. These compounds emit
from purple- blue to orange-red. These compounds are amorphous with glass
transition temperatures ranging from 104 to 170 oC and high thermal
decomposition temperature (Td > 340 oC) . Among them, EF-I-N, EF-I-N2,
SPY-I-N exhibited both good electron- and hole-transporting (mobilities ~10-5
