Novel non-fluorescent rhodamines |
abstract |
A novel non-fluorescent rhodamine dye forms a twisted intramolecular charge transfer state. A substituent that causes steric hindrance is introduced at an ortho position of a dimethylamino group on the xanthene ring of tetramethylrhodamine, which is a general rhodamine that exhibits strong fluorescence, and a certain amount of twist is imparted in a ground state. As a result, the formation of the twisted intramolecular charge transfer state is promoted in the excited state and non-fluorescence is exhibited. |
