Abstract

Measurements on a rather rigid and coplanar bichromophoric compound have been carried out with respect to intramolecular charge separation, as well as regarding solvation and lifetime of the CT state in alcohol solutions. The results indicate that the CT step proceeds very efficiently followed by a Stokes shift of the CT emission band governed by the dielectric relaxation of the solvent (a series of n-alcohols). The average Stokes-shift time, τsolv (of a ...
