Chain-Growth Polymerization of 2-Chlorothiophenes Promoted by Lewis Acids
摘要:
Lewis acids promote the polymerization of several 2-chloroalkylenedioxythiophenes, providing high-molecular-weight conjugated polymers. The proposed mechanism is a cationic chain-growth polymerization, as confirmed by end-capping reactions and a linear correlation of molecular weight with percent conversion. The "living" character of this process was used to prepare new block copolymers.

A method for forming an electrochromic polymer block includes: forming each of reaction units by reacting two or more electron-donor groups, wherein each of the reaction units includes (i) a first backbone formed by the two or more electron-donor groups and (ii) at least one reactive functional group connected to each end of the first backbone; and forming the electrochromic polymer block by reacting at least two of the reaction units with acid-catalyzed cationic polymerization, wherein the electrochromic polymer block includes a second backbone formed by two or more of the first backbones.
