| 摘 要： | 近年来，在分子内电荷转移化合物发光行为的研究中，对分子激发态非辐射衰变通道问题的研究有了较大的进展［‘－’］．在分子结构和所处环境两因素对激发分子非辐射衰变过程影响的研究中，在结构方面已经认识到如化合物分子内双键的特性、杂原子的存在以及分子的几何构象等都可能对化合物的发光行为带来很大影响［’－’1．特别是分子立体几何构象问题，自F6rster－Hoffmarm提出他们的模型以来同，最近迅速发展起来的所谓“扭曲的分子内电荷转移（TICT）”概念同，使分子构象问题在荧光、激光染料的光物理研究中占有十分重要的位置．按…

| Abstract: | The Iluorescence quantum yields and lifetfors T of 1,5-diphenyl-3 naphthyl-2-pyrazoline were measured in methanol/glycerol and cyclohexane/llquid paraf fin Anxed systems at 288K. Results indicated that the ratio T/ .f was found to be viscosity independent and equal to the intrinsic radiative lifetime Th calculated from the integrated absorption spectra. In addition, the process of nonradiative decay of the title compound TPP was discussed. |
