the target compound are extremely sensitive to changes in solvent polarity since the lowest-energy excited states possess considerable charge-transfer character. Excitation results in a greatly increased dipole moment, with the resultant excitedsingletstate retaining a lifetime of ca. 1 ns in all solvents. Radiative decay involves coupling between the lowest-energy excitedsingletstate and both the
