Anion-binding interactions are prevalent in nature but not commonly used in polymerizations. Now, an anion-binding catalytic strategy for living cationic polymerization is reported. Selenocyclodiphosph(V)azanes act as hydrogen-bond donors to reversibly activate dormant covalent bonds, and enable control of the equilibrium between the dormant and active species, which ensures precision polymer synthesis.
