  Transition-Metal-Free Controlled Polymerization of 2-Perfluoroaryl-5-trimethylsilylthiophenes

  摘要：

  A catalytic amount of fluoride anion promoted the polymerization of 2-pentafluorophenyl-5-trimethylsilylthiophene, providing a high-molecular-weight conjugated polymer in a chain-growth-like manner. The resulting polymer with a controlled molecular weight and a low molecular weight distribution was obtained in a high yield. The mechanism involves a pentacoordinated fluorosilicate as a key intermediate. The active polymerization end also initiated the second polymerization to afford well-defined block copolymers.
