摘要
A 9,10-bisphenylphenanthrene derivative has a structure of formula (1):; , wherein P1 and P2 are substituted or non-substituted polycyclic aromatic hydrocarbons (PAH), and R is a member selected from the group consisting of H, halo, cyano, trifluoromethyl, amino, C1-C10 alkyl, C2-C10 alkenyl, C2-C10 alkynyl, C3-C20 cycloalkyl, C3-C20 cycloalkenyl, C1-C20 heterocycloalkyl, C1-C20 heterocycloalkenyl, aryl and heteroaryl. The 9,10-bisphenylphenanthrene derivative of the present invention may function as a host emitter to be used in an organic light emitting device with advantages such as higher efficiency, lower operating voltage, higher brightness and higher thermal stability.展开▼
