EXCITED-STATE DIPOLE MOMENT AND SOLVATOCHROMISM OF HIGHLY FLUORESCENT ROD-SHAPED BICHROMOPHORIC MOLECULES.

Article abstract of DOI:10.1021/ja00334a011

Efficient photoinduced charge separation can occur in molecules containing electron donor (D) and acceptor (A) groups separated by an elongated paraffinic spacer. For two molecules of this type the dipole moment of the excited state thus achieved (D** plu
