Topochemical reactions normally occurring in the solid and crystalline state exhibit solvent-free catalyst-free properties, with high atom economy which have been widely applied materials science polymer synthesis. Herein, we explore potential of topochemical for controlling emergence supramolecular chirality precise fabrication chiroptical materials. Boronic acid pinacol esters (BPin) were conjugated to naphthalimides containing an inherent chiral cholesteryl group linked by alkyl or benzene spacers. The BPin segments oxidized H2O2 form hydroxyl groups, enhanced luminescence, reduced steric effects, increased amphiphilicity. liposomal aggregates underwent situ oxidation transformed into 1D nanoarchitectures, exhibiting macroscopic chirality, active Cotton circularly polarized luminescence. Oxidation could also initiate intimate interplay between building units guest molecule, evolution multiple component assembly system realized.
