Ionic H-bonding organocatalysts for the ring-opening polymerization of cyclic esters and cyclic carbonates

Ring-opening polymerization (ROP) of cyclic monomers is a prevalent and convenient method for the synthesis of well-defined polymers with initiators/catalysts that promote a nucleophilic or electrophilic attack on the monomers. Selective activation of functional groups or linkages of the monomer without those carried out in the polymer chains, especially at high conversion, is one of the challenges faced by ROP catalysts. H-bonding...
