Carbazole derivative and semiconductor nanocrystal |
摘要 |
A carbazole derivative represented by the following General Formula (1) where at least one aromatic ring has one to three substituents each represented by the following General Formula (2):;in General Formula (1), Ar1 and Ar2 each independently represent a substituted or unsubstituted aryl group which may form a ring with a benzene ring, a substituted or unsubstituted heterocyclic group, a substituted or unsubstituted arylsilyl group, or a hydrogen atom, and Ar3 represents a substituted or unsubstituted aryl group,
—X—Y—Z (2)in General Formula (2), X represents a methylene group, a carbonyloxy group, an oxycarbonyl group, a carbonyl group, an oxygen atom or a sulfur atom, Y represents a substituted or unsubstituted alkylene group, and Z represents a carboxyl group, a hydroxyl group or a thiol group. |
