Abstract

The reactions of interaction of N,N'-di(4-chlorophenyl)diimide 1,1'-binaphtyl-4,4',5,5',8,8'-hexa-carboxylic acid (cubogen red) with thiourea dioxide in a water-alkaline solution and a Langmuir–Blodgett thin film, obtained on quartz and silicon substrates, have been investigated. Electron absorption spectroscopy have revealed that the reaction of reductive cyclization of cubogen with formation of perylenetetracarboxylic acid diimide derivatives occurs in a water-alkaline solution. At the same time, the interaction of thiourea dioxide with a cubogen thin film does not lead to the formation of cyclization products; nevertheless, it changes the film structure. One might suggest that soluble leuco forms of J aggregates are formed in this case, whereas H aggregates remain intact in the structure.

N，N'-二（4-氯苯基）二酰亚胺1,1'-联萘基-4,4'，5,5'，8,8'-六羧酸与硫脲二氧化物在溶液和薄膜中的相互作用

摘要

N，N相互作用的反应'-二（4-氯苯基）二酰亚胺1,1'-联萘基-4,4'，5,5'，8,8'-六元羧酸（cubogen red）与二氧化硫脲在水-碱性溶液中和研究了在石英和硅衬底上获得的Langmuir-Blodgett薄膜。电子吸收光谱表明，在水-碱性溶液中发生了立方晶的还原环化反应与formation四羧酸二酰亚胺衍生物形成的反应。同时，二氧化硫脲与长方体薄膜的相互作用不会导致环化产物的形成。但是，它改变了膜的结构。一个人可能暗示在这种情况下形成了J聚集体的可溶性无色形式，而H聚集体在结构中保持完整。
