摘要:
Sulfur, the sixth abundant nonmetal element in the earth, is widely exists in a variety of food ingredients, agrochemicals, and natural medicines. To date, using in-depth studies of sulfur chemistry, diversified chemical transformation strategies have been developed to synthesize a variety of sulfur-containing compounds, such as urea, episulfide, and a large category of sulfur-containing medicinal compounds. Also, the incorporation of sulfur atoms into the polymer backbone has captured the attention of polymeric chemistry scientists, as the newly induced sulfur atoms endow the polymer with accessional attractive properties, e.g., enhanced thermodynamic properties, and excellent optical and electronic properties. These excellent properties result in their wide applications. Herein, we would like to briefly introduce our recent research about the precise synthesis of degradable sulfur-containing polymer, including polythiocarbonates and polythioesters.
