The biaryl scaffold is of great importance in many fields, such as biologically active molecules and materials. Lately, its synthesis has been greatly facilitated by the advent of crosscoupling reactions. Nevertheless, the development of more step-and ato

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.)

The orientation of Ar-C, Ar-N and Ar-O bonds in biaryls, N,N′-diarylureas and diaryl ethers (whose conformers are distinguishable by NMR) may be controlled with a selectivity up to >95: 5 by an adjacent stereogenic centre; the selectivity may be greater when a second stereogenic axis is inserted between the controlling centre and the slowly rotating bond.
