Intramolecular photoinduced electron transfer for cations derived from azole-substituted coumarin dyes

[摘要] The conjugate acids of 7-aminocoumarins that are substituted with benzimidazole or benzothiazole groups display long wavelength absorption and emission associated with low-lying charge transfer states; rapid radiationless deactivation is proposed to proceed via TICT-type intermediates.
