7-diethylamino coumarins exhibit large enhancement of fluorescence yield upon binding to bovine serum albumin. It is argued that the polarity-dependent twisted intramolecular charge transfer (TICT) process is responsible for the remarkable fluorescence sensitivity of these biological fluorophores to
