Intramolecular electron donor–acceptor complexes as a model for excited termolecular complexes
Abstract
The fluorescence spectra of three triple-layered and one double-layered compounds (1)–(4) were investigated; it is concluded from the solvent effects on the spectra that the stacking arrangement donor-donor-acceptor (DDA) is relevant to the structure of intermolecular 2 : 1 complexes in the excited state.
