Abstract
AbstractWe report the straightforward synthesis of photoreactive nanoobjects exhibiting various colloidal morphologies by photoinitiated polymerization‐induced self‐assembly (PISA). Poly(oligoethylene glycol methyl ether methacrylate) copolymers with pendent UV‐activatable diaryl tetrazole moieties were employed as macromolecular chain‐transfer agents in water for the dispersion photopolymerization of 2‐hydroxypropyl methacrylate under visible light. This led to the in situ formation of amphiphilic block copolymers, driving the self‐assembly into core‐shell nanoparticles, nanofibers, and nano/microvesicles. The tetrazole group present in the shell of the nanoobjects permitted functionalization with various functional molecules and polymers via UV‐triggered nitrile imine‐mediated tetrazole–ene cycloaddition (NITEC), enabling the alteration of surface properties of the nanomaterials (fluorescence, charge, hydrophilicity).
