Furthermore, in terms of obtaining a high luminous efficiency, the groups other than a hydrogen atom in RP1 to RP10 are preferably an aromatic hydrocarbon group which may have a substituent or a silyl group which may have a substituent, with an aromatic hydrocarbon group which may have a substituent being especially preferable. Moreover, in terms of obtaining emission with a narrow half-value width, the groups other than a hydrogen atom in RP1 to RP10 are preferably an alkyl group which may have a substituent, an arylamino group which may have substituent, or a heterocyclic group which may have a substituent, and in terms of obtaining a longer emission wavelength, the groups other than a hydrogen atom in RP1, RP3 to RP6, and RP8 to RP10 are preferably an aromatic hydrocarbon group which may have a substituent or a heterocyclic group which may have a substituent.
The aromatic hydrocarbon groups represented by RP1 to RP10 are preferably with a carbon number of 6 to 16, and these are not limited at all to being monocyclic groups and may instead be condensed polycyclic hydrocarbon groups. Concrete examples of aromatic hydrocarbon groups include a phenyl group, a biphenyl group, a phenanthryl group, a naphthyl group, an anthryl group, and a fluorenyl group.
The alkyl groups represented by RP1 to RP10 are preferably with a carbon number of 1 to 10, and concrete examples include an i-propyl group, a t-butyl group, and a cyclohexyl group.
