Colloidal lead halide perovskite nanocrystals (PNCs) suffered from interface instability in polar media and therefore limited the use of them in real applications. In this presentation, we discussed our recent progress on using in-situ surface-initiated photoinduced electron transfer reversible addition−fragmentation chain-transfer (SI-PET-RAFT) polymerization to protect and functionalize the PNCs, in which the PNCs functioned as both photocatalysts and substrates for the growth of polymers. In particular, we will focus on the optimization of stability of produced PNC-polyacrylates nanocomplex by tuning the PNC-polyacrylates interface linkage, surface polymer molecular weight and side chain structure. We believe this research will provide insights for rational design and “bottom-up” fabrication of polar-solvent-tolerant PNC-polymer nanocomplex.
