✦ Synopsis

Intrapolymer

electron transfer from the higher excited to the neighbouring ground states of pyrenyl chromophores occurs rapidly in polyesters. This charge separation process is characteristic of polymers and was not observed in the studies on bichromophoric model compounds.

Relative geometrical structures of the relevant chromophores are discussed by comparing the results with those of polypeptides having the same chromophore.
