Controlled Ring-Opening Polymerization of L-Lactide Triggered by Supramolecular Organocatalytic Systems

In this paper, we describe our last discoveries concerning new original organocatalytic systems that take advantages of supramolecular interactions to trigger the Ring-Opening Polymerization of L-lactide. (Thio)Amidoindoles and N,N-dimethylaminopyridine based systems proved to be efficient catalysts that allow an excellent control of the polymerization. In all cases, dual activation of the monomer and the polymer growing chain-end was demonstrated.
