激基复合物的形成是很多荧光猝灭的中间过程,也是光化学反应和生物分子的光化学转变的中间状态,并且是有机光导体光生载流子的中间体,因此激基复合物的研究是一个十分活跃的领域。但对于有机分子和无机酸分子之间相互作用形成激基复合物,特别是形成三分子激基复合物还极少报道,而这一过程对深入了解生物分子的光化学转变,光合作用机理等有着重要的意义。本文研究了苯甲酸乙酯的光物理过程,发现了苯甲酸乙酯浓溶液可以形成激基缔合物。苯甲酸乙酯不仅能与硫酸分子作用形成1∶1的双分子激基复合物,还可以和硫酸分子形成2∶1的三分子激基复合物。并讨论了形成三分子激基复合物的两种途径。
The formation of an exciplex is an intermediate process of many fluorescence quenching and is also an intermediate state between photochemical reactions and photochemical transformation of biomolecules and is an intermediate of photogenerated carriers of organic photoconductors. Therefore, the study of exciplexes is a Very active area. However, the formation of exciplexes for the interaction between organic molecules and inorganic acid molecules, and especially the formation of three-molecule exciplexes, are seldom reported, and this process is of great interest in understanding the photochemical transformation of biomolecules and the mechanisms of photosynthesis Significance. In this paper, the photophysical process of ethyl benzoate was studied and it was found that ethyl benzoate concentrated solution can form excimer. Ethyl benzoate can not only form a 1: 1 bimolecular complex with the sulfuric acid molecule, but also form a 2: 1 tri-molecular excimer complex with the sulfuric acid molecule. Two approaches to the formation of the three-molecule exciplex are discussed.
