A simple and direct method for derivatization of solid polysaccharides is presented. The novel methodology is based on the combination of organic acid-catalyzed esterification or etherification and photochemical thiol-ene click derivatization of a heterogeneous polysaccharide. The solid cellulose was "organoclick" modified with aryl, alkyl and polyester groups, respectively. The modification allows for a highly modular and metal free surface modification of solid polysaccharides.
本文提出了一种用于固体多糖衍生化的简单直接方法。该新方法基于有机酸催化的酯化或醚化与多相多糖的光化学硫醇-烯点击衍生化相结合。固体纤维素分别用芳基、烷基和聚酯基团进行了“有机点击”修饰。这种修饰实现了固体多糖的高度模块化且无金属的表面修饰。
