Abstract
An organic light-emitting device having a compound represented by the following general formula in a light-emitting layer thereof has a high light emission efficiency. R1 to R5 each independently represent a hydrogen atom or a substituent having a Hammett σp value of 0 or more. R6 to R20 each independently represent a hydrogen atom or a substituent, provided that at least one of R6 to R20 represents a substituted or unsubstituted N,N-diarylamino group. m represents 1 or 2.
Claims13
A light-emitting material comprising a compound represented by the following general formula (1):
- wherein in the general formula (1), R1 to R5 each independently represent a hydrogen atom or a substituent having a Hammett σp value of 0 or more;
- R6 to R20 each independently represent a hydrogen atom or a substituent, provided that at least one of R6 to R20 represents a substituted or unsubstituted N, N-diarylamino group;
- and m represents 1 or 2.
A compound represented by the following general formula (11):
- wherein in the general formula (11), R1′ to R5′ each independently represent a hydrogen atom or a substituent having a Hammett σp value of 0 or more;
- R6 to R20 each independently represent a hydrogen atom or a substituent, provided that at least one of R6′ to R20′ represents a substituted or unsubstituted N,N-diarylamino group;
- and m′ represents 1 or 2.
