Fluorescence Depolarization Kinetics of Neutral and Charged 2-(3′-Pyridyl)oxazole

The results of measurements of the starionary and time-resolved flurescence anisotropy and of the AM1 and INDO/S calculations were used for conformational analysis of a neutral molecule of the 2-(3′-pyridyl)oxazole series and of its N-ethyl cation. Most probably, the excitation of the quasi-planar rotamers of the cation, in contrast to the neutral molecule, is accompanied by a ∼90° turn of its Et-py fragment with the formation of a twisted charge-transfer conformation. According to the data obtained for ethanol and glycerol solutions and for the poly(methyl methacrylate) matrix at 20°C, the efficiency of the intramolecular relaxation is independent of the viscosity.__________Translated from Zhurnal Obshchei Khimii, Vol. 75, No. 5, 2005, pp. 836–840.Original Russian Text Copyright © 2005 by Volchkov, Dem’yanov, Rusalov, Syreishchikova.
