Supramolecular sulfur-containing polymers with hydrogen bonding

Abstract

Although sulfur-containing polymers have been realized by various methods such as copolymerization and reverse vulcanization, there are few reports on the synthesis of supramolecular sulfur-containing polymers in which a supramolecular polymer is fused with a sulfur-containing polymer. Herein, we prepare a supramolecular sulfur-containig polymer by introducing a 2-ureido-4[1H]pyrimidinone (UPy) unit at both ends of linear sulfur and connecting between the UPys via hydrogen bonding.
