摘要

Polyisothiourea is an interesting polymer to potentially exhibit numerious properties. Herein we report the first facile synthesis of polyisothioureas via alternating copolymerization of aziridines and isothiocayanates. Mediated by the catalytic system of phosphazene superbases/alcohol, a broad scope of aziridines and isothiocayanates could be transformed into well-defined polyisothioureas (11 examples).

Abstract

Isothiourea is an important class of sulfur-containing molecules showing unique catalytic and biological activities. As such, polyisothiourea is envisioned to be an interesting type of polymer that potentially exhibits a number of interesting properties. However, there is no access to synthesizing well-defined polyisothiourea, and currently isothiourea-containing polymers are mainly prepared by immobilizing onto other polymer’s side chain. Herein, we report the first facile synthesis of polyisothioureas ,via, alternating copolymerization of aziridines and isothiocayanates. Mediated by the catalytic system of phosphazene superbases/alcohol, a broad scope of aziridines and isothiocayanates could be transformed into polyisothioureas with adjustable substitutions (11 examples). The structures of obtained polyisothioureas were fully characterized with ,1,H-NMR,13,C-NMR, and ,1,H-,13,C HMBC NMR. Moreover, the polyisothioureas show tunable thermal properties depending on substitutions on the isothiourea linkages. The novel structure of these polyisothioureas will enable a powerful platform for the discovery of next-generation functional plastics.
