<p>Provided are a novel compound which can be formed into a thin layer and which exhibits excellent hole-transporting characteristics, and a light-emitting element, such as an organic EL element, which has an organic layer containing the compound. Specifically provided is a compound represented by the formula. [therein, the C1, C2, and C3 rings represent an aromatic hydrocarbon ring or a heterocyclic ring. A represents a single bond or a divalent group. n1 represents an integer from 1 to 4, and n2 represents an integer from 0 to 4. l1 represents an integer from 0 to 3, and l2 represents an integer from 0 to 4. R1 to R3 are the same or different and represent an alkoxy group, a halogen atom, a hydrogen atom, or a hydroxyl group. X1 represents an oxygen atom, a sulfur atom, a selenium atom, or a divalent group containing at least one atom selected from among boron, carbon, nitrogen, oxygen, phosphorus, sulfur, and selenium. D represents hydrogen, an alkyl group, an alkoxy group, or an aryl group.]</p> |
