Abstract
Aspects of the present invention can provide a novel phenanthrothiadiazole compound with the lowest excited triplet level T1 that is high, the phenanthrothiadiazole compound being capable of forming a stable amorphous film. Furthermore, aspects of the present invention can provide an organic light-emitting device having high luminous efficiency and a low driving voltage. Aspects of the present invention provide a phenanthrothiadiazole compound represented by one of general formulae [1] to [3] according to Claim 1.
Claims13
A phenanthrothiadiazole compound represented by one of general formulae [1] to [3]:
- wherein in each of general formulae [1] to [3],
- Ar represents a phenyl group, a phenanthryl group, a fluorenyl group, or a triphenylenyl group;
- the substituent represented by Ar is unsubstituted or substituted with an alkyl group having 1 to 4 carbon atoms, a phenyl group, a phenanthryl group, a fluorenyl group, or a triphenylenyl group;
- R1 represents an alkyl group having 1 to 4 carbon atoms, n represents an integer of 0 to 3, and when n represents 2 or 3, alkyl groups represented by plural R1's may be the same or different;
- and
- R2 and R3 each independently represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms.
