9,9-DIPHENYLFLUORENE COMPOUND AND ORGANIC ELECTROLUMINESCENT DEVICE CONTAINING THE 9,9-DIPHENYLFLUORENE

摘要

PROBLEM TO BE SOLVED: To provide new 9,9-diphenylfluorene compounds and organic electroluminescent devices having a long emission life and excellent durability. SOLUTION: The 9,9-diphenylfluorene compounds are represented by formula (1) (wherein R1 to R3 are each hydrogen, an alkyl group, an aryl group, an aralkyl group or the like; Z1to Z6are each hydrogen, a halogen, an alkyl group, an alkoxy group, an amino group, an aryl group, an aralkyl group or the like; Z7is hydrogen, a halogen, an alkyl group, alkoxy group, an aryl group or an aralkyl group; and Z1to Z6may be bonded to each another to form a ring).
