Renewable, fluorescent, and thermoresponsive: cellulose copolymers via light-induced ligation in solution

Abstract

We introduce a mild photochemically driven strategy for the synthesis of fluorescent cellulose copolymers using filter paper as the starting material. Thermoresponsive behaviour in water is imparted to the brush-like structures by grafting of poly(N-isopropylacrylamide) side chains. All reactions take place in homogenous solutions, allowing the design of novel advanced materials from renewable resources.
