By　virtue　of　noninvasive　regulations　by　light,　photocontrolled　polymerizations　have　attracted　considerable　attention　for　the　precision　synthesis　of　macromolecules.　However,　a　cationic　polymerization　with　simultaneous　photocontrol　and　tacticity-regulation　remains　elusive　so　far.　Herein,　we　introduce　an　asymmetric　ion-pairing　photoredox　catalysis　strategy　that　allows　for　the　development　of　a　stereoselective　cationic　polymerization　with　concurrent　light　regulation　for　the　first　time.　By　employing　an　ion　pair　catalyst　(PC+/*A(-))　consisting　of　a　photoredox　active　cation　(PC+)　and　a　sterically　confined　chiral　anion　(*A-)　to　deliver　the　stereochemical　control,　the　cationic　polymerization　of　vinyl　ethers　can　be　achieved　with　photocontrol　and　high　isotactic　selectivity　(up　to　91%　m)　at　a　remarkable　low　catalyst　loading　(50　ppm).
