分子内电荷转移化合物的光谱和光物理

THE SPECTRA AND PHOTOPHYSICS OF THE INTRAMOLECULAR CHARGE TRANSFER COMPOUND

近年来,分子内电荷转移化合物光物理行为的研究受到了广泛的注意,这是由于这类化合物分子的发光性能强烈地受其周围溶剂性质的影响.它们常被考虑作为研究溶剂-溶质间相互作用以及溶剂分子弛豫的有效探针化合物.Loutfy等曾对被束缚的及未被束缚的N,N-二甲基氨基苄叉二腈类化合物的光物理行为作过详细研究.指出它们的荧光量子产率和该类化合物分子的刚性以及和母体环境的粘度、温度及物理化学性质等密切有关。

The photophysical behavior of titled compound has been studied. Results show that the fluorescence spectra and the fluorescence quantum yields depend strongly on the polarity and the viscosity of solvents. The rate constants of the radiation and ra-diationless decay processes of the excited compound were calculated. A comparativestudy has been carried out between compounds which possess binding and unbindingstructures respectively.
