本文在Grabowski模型基础上,提出了一种描述TICT态生成动力学的理论模型,并采用时间相关单光予计数荧光光谱方法,测量了香豆素C1F和C2F在醇类溶剂中的荧光寿命,考察了各种溶剂效应(极性、粘度和温度)对TICT态生成速率的影响,并将结果与DSE关系比较,指出在醇类溶剂中,氢链效应的影响是十分重要的.
Based on the Grabowski model, a theoretical model describing the kinetics of TICT state generation is proposed. Fluorescence lifetime of coumarin C1F and C2F in alcoholic solvents is measured by time-dependent single-light pre-count fluorescence spectroscopy. The effect of various solvent effects (polarity, viscosity and temperature) on the formation rate of TICT state was investigated. The results were compared with that of DSE. It was pointed out that the influence of hydrogen chain effect in alcohol solvents was very important.
