Page/Page column 31-32, (2009/01/24)
A novel material having high hole-transporting ability and a high glass transition temperature and having long-lasting durability is obtained. A benzofluorene compound represented by formula (1) is used. (In the formula, M is a substituted or unsubstituted aryl group having 6-40 carbon atoms or a substituted or unsubstituted heteroaryl group having 5-40 carbon atoms; Ar1 to Ar4 each independently is a substituted or unsubstituted aryl group having 6-40 carbon atoms or a substituted or unsubstituted heteroaryl group having 5-40 carbon atoms, provided that at least one of Ar1 to Ar4 is a substituent represented by any of the following formulae (2) to (5); and p is an integer of 0-2.) (In the formulae, R1 to R4 each independently is a hydrogen atom, a halogen atom, a substituted or unsubstituted amino group, a linear, branched, or cyclic alkyl group, a linear, branched, or cyclic alkoxy group, a substituted or unsubstituted aryl group having 6-40 carbon atoms, or a substituted or unsubstituted aryloxy group having 6-40 carbon atoms, provided that R1 and R2 may be bonded to each other to form a ring.)
