摘要：
A material for organic electroluminescent elements having a high luminescent efficiency, a long life, and high heat resistance; and a process for producing the material. The material is represented by gereral formula (1). In the formula, A represents optionally substituted C22-60 arylene; X1 to X4 each represents optionally substituted C¿6-30? arylene; Y?1 to Y4¿ each represents an organic group represented by general formula (2); and a to d each is 0 to 2. In the formula, R1 to R4 each represents hydrogen, optionally substituted alkyl or aryl, or cyano, provided that R3 may be bonded to R4 to form a triple bond; Z represents optionally substituted aryl; and n is 0 or 1.
