Abstract

In this report, the design and synthesis of cholesterol-based sugar azobenzene derivatives as photo-responsive organogelators have been carried out. The gel formation in different solvents was examined, and a minimum CGC of 0.5 % (w/v) was attained in toluene. The mechanism of self-assembly of organogels was characterized by using ¹H NMR, UV–Vis, FT-IR, and PXRD. These organogelators show photo-isomerization and photo-reversible properties, which were studied using absorption spectra. Computational studies studied the optimized dimer structures and geometries of the trans and cis isomers. The prominent nature of this designed structure makes it an outstanding, intelligent soft material with plausible applications.

含糖偶氮苯衍生物的胆固醇光反应有机凝胶

本文设计并合成了以胆固醇为基础的糖偶氮苯衍生物作为光反应性有机凝胶。考察了不同溶剂中凝胶的形成情况，在甲苯中，CGC最低为0.5% （w/v）。采用1H NMR、UV-Vis、FT-IR、PXRD等手段对有机凝胶的自组装机理进行了表征。这些有机凝胶具有光异构化和光可逆性质，并利用吸收光谱对其进行了研究。计算研究了优化的二聚体结构和顺式异构体的几何形状。这种设计结构的突出性质使其成为具有合理应用的杰出智能软材料。

期刊介绍： Carbohydrate Research publishes reports of original research in the following areas of carbohydrate science: action of enzymes, analytical chemistry, biochemistry (biosynthesis, degradation, structural and functional biochemistry, conformation, molecular recognition, enzyme mechanisms, carbohydrate-processing enzymes, including glycosidases and glycosyltransferases), chemical synthesis, isolation of natural products, physicochemical studies, reactions and their mechanisms, the study of structures and stereochemistry, and technological aspects. Papers on polysaccharides should have a "molecular" component; that is a paper on new or modified polysaccharides should include structural information and characterization in addition to the usual studies of rheological properties and the like. A paper on a new, naturally occurring polysaccharide should include structural information, defining monosaccharide components and linkage sequence. Papers devoted wholly or partly to X-ray crystallographic studies, or to computational aspects (molecular mechanics or molecular orbital calculations, simulations via molecular dynamics), will be considered if they meet certain criteria. For computational papers the requirements are that the methods used be specified in sufficient detail to permit replication of the results, and that the conclusions be shown to have relevance to experimental observations - the authors'' own data or data from the literature. Specific directions for the presentation of X-ray data are given below under Results and "discussion".
