Abstract
A compound represented by the following formula (1): wherein in the formula (1), Ar1 and Ar2 are independently a substituted or unsubstituted aryl group, a substituted or unsubstituted heteroaryl group, or a substituted or unsubstituted alkyl group; X1 to X4 and X13 to X16 are independently CR1, CH or N; one of X5 to X8 is a carbon atom bonding to one of X9 to X12, and at least one of X5 to X8 that is adjacent to the carbon atom bonding to one of X9 to X12 is CR2; one of X9 to X12 is a carbon atom bonding to one of X5 to X8, and X9 to X12 that is adjacent to the carbon atom bonding to one of X5 to X8 is CH or N; and the remaining X5 to X8 and the remaining X9 to X12 are CR1, CH or N.
