Abstract
A high light emission efficiency can be achieved by the use of a compound represented by the general formula (1) as a host material or a light-emitting material of a light-emitting layer of an organic light-emitting device. X1 to X12 each independently represent C or BH constituting carborane, provided that among X1 to X12, the bonding positions to A and D each represent C, and the other thereof each represent BH; A represents an acceptor bonded to the carborane through an aromatic ring or a heteroaromatic ring; and D represents a donor bonded to the carborane through an aromatic ring or a heteroaromatic ring.
