用从头算方法研究了实验合成的具有强荧光的2-芳基取代吲哚类化合物2-苯基吲哚(2 PI)、2-萘基吲哚(2NI)和2-蒽基吲哚(2AI)的结构和光物理过程。结果表明,实验测得的光吸收和荧光对应于吲哚NH端去质子化的一价阴离子,而不是中性化合物。在光化学反应过程中,吲哚和2-芳基取代基的平面夹角保持不变,但阴离子可立即发生光诱导的分子内电荷转移。并利用线性反应坐标分析了光激发后的光物理过程。
Ab initiomethod is used to figure out the structures and photo-physical processes of 2-aryl substituted indoles, 2-phenylindole (2PI), 2-naphthylindole (2NI), and 2-anthracenylindole (2AI), synthesized experimentally with strong fluorescence. The results show that the photoabsorption and fluorescence measured experimentally correspond to the monovalent anions deprotonated in the indole NH end, other than the neutral compounds. During the photochemical reaction, the angles between the planes of the indole and 2-aryl substituted moieties keep unchanged, but the photo-induced intramolecular charge transfer can immediately occur in the anions. Furthermore, the photo-physical processes after photoexcitation are analyzed by using a linear reaction coordinate.
