An amphiphilic block copolymer PNIPAM53‐b‐(PS30‐co‐P4AMS10) was facilely prepared by reversible addition‐fragmentation chain transfer (RAFT) polymerization. The immobilization of (S)‐α,α‐diphenylprolinol trimethylsilyl ether onto the block copolymers was then performed through using copper‐catalyzed alkyne‐azide cycloaddition (CuAAC), and the generating amphiphilic diblock copolymer supported chiral catalyst PNIPAM53‐b‐(PS30‐co‐P4AMS10)/proTMS was self‐assembled into micelles with regular diameters about 50 nm in aqueous solution. The micellar catalyst was further used for the asymmetric Michael reaction between propanal and trans‐β‐nitrostyrene in water. Using only 1 mol% micellar catalyst, the corresponding Michael addition products could be obtained in good yields and high enantioselectivities as well as good diastereoselectivities. In addition, this micellar catalyst could be reused at least for four times. Moreover, the micellar catalyst could be applied for the asymmetric addition reaction of 4‐chlorocinnamyl aldehyde and nitromethane, and thus constructing the baclofen pharmaceutical intermediate.

We report a facile strategy for incorporating persistent and effective antibacterial property into a widely used polymer, poly(methyl methacrylate) (PMMA), by copolymerizing methyl methacrylate (MMA) with 2-(tert-butylamino)ethyl methacrylate (TA) in one pot via atom transfer radical polymerization (ATRP). The subsequent self-assembly of the resultant poly(methyl methacrylate)-block-poly[(2-tert-butylamino)ethyl methacrylate] (PMMA 20 -b-PTA 15 ) diblock copolymer affords well-defined water-dispersible vesicles, which can be facilely sprayed on the walls in hospitals for effective inhibition and killing of bacteria. 1 H-NMR and gel permeation chromatography (GPC) studies confirmed the successful synthesis of welldefined copolymer. Transmission electron microscopy (TEM), atomic force microscopy (AFM) and dynamic light scattering (DLS) studies proved the formation of vesicles with narrow size distribution. DLS studies revealed the excellent stability of vesicles at various temperatures. Antibacterial tests showed effective antibacterial activities of polymer vesicles against both Gram-positive and Gram-negative bacteria. Moreover, this strategy may be extended for preparing a wide range of polymeric materials for facile antibacterial applications in many fields.
