Triarylsulfonium hexafluorophosphate salts as photoactivated acidic catalysts for ring-opening polymerisation

Triarylsulfonium hexafluorophosphate salts were shown to be effective catalysts for the ring-opening polymerisation of various cyclic monomers under UV irradiation. A dual basic/acidic catalytic system demonstrated the potential for UV-triggered formation of poly(δ-valerolactone)-b-poly(L-lactide)-b...

Zusammenfassung:Triarylsulfonium hexafluorophosphate salts were shown to be effective catalysts for the ring-opening polymerisation of various cyclic monomers under UV irradiation. A dual basic/acidic catalytic system demonstrated the potential for UV-triggered formation of poly(δ-valerolactone)-b-poly(L-lactide)-b-poly(δ-valerolactone) in a 'one-pot' reaction.
