Cellulose graft copolymers are an effective way to endow new properties to cellulose substrate, as well the rigidity, regularity, and helicity of the cellulose backbone could induce the self-assembly of supramolecular structures. In this work, right-handed helical poly(phenyl isocyanide)s (PPIn) were grafted selectively onto C-6-cellulose. Alkyne-terminated PPIn was synthesized by living polymerization of right-handed phenyl isocyanide monomer using an alkyne-terminated palladium(II) complex as an initiator/catalyst, and were grafted onto the C-6 of the cellulose backbone (Cell 6 g PPIn) at various chain lengths using copper-catalyzed alkyne-azide cycloaddition (CuAAC) click chemistry. We confirmed the successful grafting by liquid H-1 NMR and C-13 NMR, as well as solid C-13 NMR, FTIR, and GPC. After grafting onto cellulose, the right-handed chirality of PPIn was significantly increased by 111.2%. Additionally, the Cell 6 g PPIn exhibited better chiral recognition of L-PheDNSP than PPIn alone. Therefore, the helical cellulose backbone has enhanced effect on preferred helix of PPIn.
