ORGANIC ELECTROLUMINESCENCE ELEMENT AND COMPOUND USED THEREIN |
摘要 |
An organic electroluminescence element in which a compound represented by the general formula below is used in a light-emitting layer exhibits a high emission efficiency and is inexpensive to provide. At least one of R 1 to R 8 and R 17 represent an electron-donating group and the others represent a hydrogen atom; at least one of R 9 to R 16 represent an electron-withdrawing group that does not have an unshared electron pair at the ±-position thereof and the others represent a hydrogen atom; Z represents a single bond or >C=Y; Y represents O, S, C (CN) 2 or C(COOH) 2 ; provided that when Z is a single bond, then at least one of R 9 to R 16 is an electron-withdrawing group that does not have an unshared electron pair at the ±-position thereof. |
