Advanced organocatalytic synthesis methods were employed to prepare linear poly(carbonate)s with control over functional group incorporation and molecular weight. Pendant allyl or epoxide groups served as reaction partners in thiol-ene click or epoxide-amine reactions with ethylene oxide-containing crosslinking groups to form a panel of six novel poly(carbonate) nanosponges with crosslinking densities ranging from 5%, 10% and 20% via an intermolecular chain-crosslinking approach.
