摘要:
Light-emitting compounds of general formula [1], wherein each of A 1 to A 4 is a substituted or unsubstituted aryl group having 6 to 16 carbon atoms, and each of R 1 to R 8 is independently a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted aryl group or a substituted or unsubstituted amino group, provided that adjacent substituents may form an aryl ring useful as a light-emitting material in an organic electroluminescence device, and organic electroluminescence device containing them.
摘要:
A light-emitting material which serves to emit light having a high brightness and is almost free of deterioration in light emission, and an organic EL device for which the light-emitting material is adapted, the material having the formula (1)
摘要:
A compound suitable for use in an electroluminescence device, having hole-injecting capability and durability and having the formula [I], [II] or [III] wherein R 1 to R 17 are organic residues, X 1 to X 18 are heteroatoms and A 1 and A 2 are chemically rational organic residues composed of C, H and O atoms or of C, H, O and S atoms, having molecular weight of 500 or less.
