Abstract
We have studied the fluorescence decay kinetics of polyester yellow in solutions and in polymers. The fluorescence of the dye in glycerol could be fitted with a sum of three exponential decays, which corresponds to three conformers differing in the orientation of the malononitrile group with respect to the dialkylaminophenyl group. At high concentrations of the dye, a ground state dimerization was observed for the first time in non-polar solvents and in polymers. From their fluorescence decay kinetics, two different configurations were identified.
