Application
Thiophene is an essential precursor to synthesize a wide range of conjugated organosulfur moieties, sulfur-containing polycyclic aromatic hydrocarbons, macrocycles, and pharmaceutical compounds. It has been widely used in the synthesis of polythiophenes and a host of active materials for organic field effect transistors (OFETs) and organic solar cells (OSCs).
