Abstract:
An organic EL device with high emission efficiency, an electronic equipment including the organic EL device, and a compound providing the organic EL device are provided. The compound is represented by formula (1): wherein Ar1 represents a substituted or unsubstituted naphthalene ring; the substituent on the naphthalene ring is at least one selected from a fluorine atom, a cyano group, an alkyl group, a cycloalkyl group, an alkoxy group, an aryloxy group, an alkylthio group, an arylthio group, a group represented by —Si(R101)(R102)(R103), and a group represented by —Z—Ra; R1 and R2 each independently represent a hydrogen atom, an alkyl group, a cycloalkyl group, a group represented by —Si(R101)(R102)(R103), an aryl group, or a heteroaryl group; R11 to R18 each independently represent a hydrogen atom, a fluorine atom, a cyano group, an alkyl group, a cycloalkyl group, an alkoxy group, an aryloxy group, an alkylthio group, an arylthio group, a group represented by —Si(R101)(R102)(R103), or a group represented by —Z—Ra; each Z represents a single bond, an arylene group, a heteroarylene group, or a divalent linking group in which 2 to 4 groups selected from the above groups are linked together; Ra represents a group represented by —N(R104)(R105), an aryl group, or a heteroaryl group; and R101 to R105 each represent a hydrogen atom, an alkyl group, a cycloalkyl group, aryl group, or a heteroaryl group; provided that at least one selected from the substituent on the naphthalene ring and R11 to R18 represents a group represented by —Z—Ra.
