Azobenzenes are photochromic molecules that possess a large range of applications. Their syntheses are usually simple and fast, and their purifications can be easy to perform. Oligosaccharide is also a wide family of biopolymer constituted of linear chain of saccharides. It can be extracted from biomass, as for cellulose, being the principal constituent of plant cell wall, or it can be enzymatically produced as for cyclodextrins, having properties not far from cellulose. Combining these two materials families can afford interesting applications such as controlled drug-release systems, photochromic liquid crystals, photoresponsive films or even fluorescent indicators. This review will compile the different syntheses of azo-dyes-grafted oligosaccharides, and will show their various applications.
偶氮苯是一种光致变色分子，具有广泛的应用。它们的合成通常简单快捷，而且它们的纯化也很容易进行。寡糖也是一种由单糖组成的生物聚合物大家族。它可以从生物质中提取，如纤维素，是植物细胞壁的主要成分，也可以通过酶法生产，如环糊精，具有与纤维素相似的性质。将这两种材料家族结合起来，可以提供有趣的应用，如控制药物释放系统、光致变色液晶、光响应薄膜甚至荧光指示剂。本文综述了不同偶氮染料接枝寡糖的合成方法，并展示了它们的各种应用。
