New crown ether-containing styryl dyes of the benzothiazole series containing an aza-15-crown-5-ether moiety were synthesized. Thetrans-cis-photoisomerization of these dyes and their analogs was studied; the effect of metal cations on the kinetics of darkcis-trans-isomerization was elucidated. The stability constants of the complexes of thecis-isomers of these dyes with Ca(ClO4)2 were estimated. The
合成了含有 aza-15-crown-5-ether 部分的苯并噻唑系列新冠醚苯乙烯基染料。研究了这些染料及其类似物的反式-顺式-光异构化;阐明了金属阳离子对暗顺反式异构化动力学的影响。估计了这些染料的顺式异构体与 Ca(ClO4)2 的络合物的稳定性常数。在从阳离子染料传递到甜菜碱时,复合物稳定性的显着增加(超过三个数量级)归因于在 N 取代基的磺基和基团之间的顺式复合物中形成了分子内键。位于氮杂冠醚部分空腔中的金属阳离子。
