This article deals with the photophysical properties of a few (anthracen-9-yl)methanamines. Analysis of absorption and the fluorescence emission spectra of these compounds indicated intramolecular photoinduced electron transfer leading to quenching of excited states, the efficiency of which depends on the geometrical constraints and electronic factors pertaining to the molecule. The decay kinetics studied using Time Correlated Single Photon Counting showed a bi-exponential decay indicating the involvement of two transient species in the excited state of these molecules. Also, we build up a relation between the rate of the photochemical reaction, free energy change and quenching of excited states.

本文讨论了一些（蒽-9-基）甲胺的光物理性质。这些化合物的吸收和荧光发射光谱分析表明，分子内光诱导的电子转移导致激发态猝灭，其效率取决于几何约束和与分子有关的电子因素。使用时间相关单光子计数研究的衰变动力学显示出双指数衰变，表明两个瞬态物质参与了这些分子的激发态。此外，我们建立了光化学反应速率，自由能变化和激发态猝灭之间的关系。
