We report a new strategy that uses N-trimethylsilyl (N-TMS) amine to mediate controlled ring-opening polymerization of amino acid N-carboxyanhydrides (NCAs). This polymerization proceeds via a unique, trimethylsilyl carbamate (TMS-CBM) propagating group that results from the cleavage of the Si-N bond of N-TMS amine followed by NCA ring opening. Propagation of the polypeptide chains proceeds thr...
We report here the integration of ring-opening metathesis polymerization (ROMP) and ring-opening polymerization of the amino acid N-carboxyanhydride (NCA) to allow facile synthesis of brush-like polymers containing polypeptide as the brush side chains. ROMP of N-trimethylsilyl norbornenes rendered the preparation of poly(norbornene)s bearing pendant N-TMS groups. With no need to purify the resu...
We developed new macromolecular engineering approaches enabling the preparation of star-shaped and antimicrobial polypeptoids by ring-opening polymerization.
Ring-Opening Polymerization-Induced Self-Assembly (ROPISA) of N -carboxyanhydride is an efficient one-step process to obtain nanomaterials made polypeptides.
Well-defined molecular brushes bearing polypeptides as side chains were prepared by a "grafting through" synthetic strategy with two-dimensional control over the brush molecular architectures. By integrating N-carboxyanhydride ring-opening polymerizations (NCA ROPs) and ring-opening metathesis polymerizations (ROMPs), desirable segment lengths of polypeptide side chains and polynorbornene brush...
