摘要： Using a compound represented by a general formula (A)m-L-(D)n, a light-emitting device having a high emission efficiency can be provided. L is an (m+n)-valent aromatic linking group; A is a group having a positive Hammett's σ p value; D is a group having a negative Hammett's σ p value; m is an integer of 1 or more; n is an integer of 2 or more. Two of plural D's differ in point of the substituent condition at specific aromatic rings.
