Abstract

The time-resolved dual-fluorescence picosecond kinetics of p-dimethylaminobenzonitrile in dodecanol, decanol, hexanol and methanol were studied. Pulse-limited rise times were found in the emission of the b* state which feeds directly the rise time of a* state emission. We found that the b* state fluorescence decay times follow the solvent viscosity. The a* state fluorescence kinetics vary with solvent and temperature, which suggests either thermally assisted intersystem crossing to a solvated triplet or thermally activated internal conversion to the ground state.
