Enzymatic synthesis and post-functionalization of two-dimensional crystalline cellulose oligomers with surface-reactive groups

Two-dimensional (2D) nanomaterials have gained considerable attention due to their unique structural and physicochemical properties. Herein, we synthesized 2D crystalline cellulose oligomers with surface-reactive azide groups through enzymatic reactions and covalently post-functionalized them with 1-ethynyl pyrene through copper(I)-catalyzed Huisgen cycloaddition reactions.
