Pg. Wiering et Jw. Verhoeven, UNPRECEDENTED OBSERVATION OF PRONOUNCED VIBRATIONAL STRUCTURE IN CHARGE-TRANSFER ABSORPTION AND EMISSION-SPECTRA, Recueil des travaux chimiques des Pays-Bas, 115(5), 1996, pp. 303
Two rigidly bridged electron donor-acceptor systems are reported that
display discrete, intramolecular charge-transfer (CT) absorption and e
mission spectra in solution at room temperature. For both the CT-absor
ption is highly structured irrespective of solvent, for one also the C
T-fluorescence in a nonpolar solvent is structured.
