Abstract
Picosecond time-resolved fluorescence spectroscopy is used to probe the formation of the twisted intramolecular charge transfer (TICT) state of 4,4'-diaminophenyl sulphone in alcohol solvents. Emission kinetics were measured in 10 nm intervals from 400 nm to 560 nm. Dynamics were measured both as a function of alkyl chain length (methanol to hexanol) and temperature in ethanol solution (25°C - 60° C). Examination of the Stoke's shifted TICT emission revealed wavelength dependent rise and decay kinetics.
