Mechanistic studies of the fluorescence quenching of 2-(2-chloro-12-oxoindolo[2,1-b]quinazolin-6(12H)-ylidene)malononitrile (2CTMA) with aniline, using solvent mixtures of acetonitrile and 1,4-dioxane at room temperature, by steady-state and time-resolved methods is reported here. It was confirmed that, with the use of the sphere of action static quenching model and finite sink approximation model, that the bimolecular quenching reactions are due to the presence of both dynamic and static quenching processes.
本文报道了在室温下，使用乙腈和1,4 - 二氧六环的混合溶剂，通过稳态和时间分辨方法对2-(2-氯-12-氧代吲哚并[2,1-b]喹唑啉-6(12H)-亚基)丙二腈(2CTMA)与苯胺的荧光猝灭进行的机理研究。通过作用球静态猝灭模型和有限阱近似模型证实，双分子猝灭反应是由动态和静态猝灭过程共同存在导致的。
