Abstract

Abstract: Fullerene polymers have attracted much attention during the past decade. To explore the synthesis of fullerene polypeptides, a fullerene— γ—benzyl L—glutamate conjugate containing a free amino group was used as an initiator, polymerization of γ—benzyl L—glutamate N—carboxy— anhydride was performed for the first time via ring—opening polymerization, leading to formation of a novel fullerene end—capped poly(γ—benzyl L—glutamate) with a yield of 37.2%. The product was characterized by 1H NMR, FTIR, UV—VIS, MALDI—TOF MS and thermogravimetric analysis. Compared with previously reported method, this route avoids utilization of azides and affords the products with relatively identical structures, highlighting its potential application in fullerene polypeptide synthesis.

Key words: Fullerene end-capped poly(γ-benzyl L-glutamate), Ring-opening polymerization, Fullerene derivative initiator
