were synthesized to mediate the metal-free polymerization of α-amino acid N-carboxyanhydride (NCA) monomer. Through the screening of catalysts, the polymerization catalyzed by the preferred bifunctional fluoroalcohol catalyst proceeded in a fast and controlled manner, affording high molecularweight polypeptide up to 35.2 × 104 Da with relatively narrow molecularweightdistribution (Đ < 1.20).
