摘要

摘要对水溶液中 3,3′-二乙基-9-甲基噻碳菁（MTCC）和 3,3′-二乙基噻碳菁（TCC）及其与葫芦[8]脲的复合物的光谱-发光特性和光谱-动力学特性进行了比较研究。TCC 与葫芦[8]脲的二聚络合物由反式异构体组成，只显示延迟荧光，而 MTCC 的二聚络合物由顺式异构体组成，在水中既显示延迟荧光，又显示磷光。MTCC 和 TCC 与葫芦[8]脲的二聚络合物参与电子光转移反应，而 MTCC 的二聚络合物参与光氧化反应的能力更强。

Molecular Photonics of 3,3'-Diethyl-9-methylthiacarbocyanine Monomers and Dimeric Complexes with Cucurbit[8]uril

Abstract

A comparative study of the spectral-luminescent and spectral-kinetic properties of 3,3′-diethyl-9-methylthiacarbocyanine (MTCC) and 3,3′-diethylthiacarbocyanine (TCC) and their complexes with cucurbit[8]uril in aqueous solution was carried out. Dimeric complexes of TCC with cucurbit [8] uril consist of trans-isomers and exhibit only delayed fluorescence while dimeric complexes of MTCC consist of cis-isomers and exhibit both delayed fluorescence and phosphorescence in water. The dimeric complexes of MTCC and TCC with cucurbit [8]uril participate in the electron phototransfer reaction where the dimeric complex of MTCC exhibits a greater ability to enter into photooxidation reactions.

期刊介绍： Optics and Spectroscopy (Optika i spektroskopiya), founded in 1956, presents original and review papers in various fields of modern optics and spectroscopy in the entire wavelength range from radio waves to X-rays. Topics covered include problems of theoretical and experimental spectroscopy of atoms, molecules, and condensed state, lasers and the interaction of laser radiation with matter, physical and geometrical optics, holography, and physical principles of optical instrument making.
