研制了一种以二烯羰基化合物为基料的多用途活性自由基聚合介质。通过对取代基的优化，制备了一种“通用”二烯羰基化合物（O4），并成功地应用于共轭和非共轭乙烯基单体的控制聚合，获得了具有预定分子量和窄分子量分布的理想聚合物，产率很高。该方法的特点是通过合成由共轭和非共轭单体组成的嵌段共聚物来证明，这对作为功能智能有机纳米材料具有重要意义。此外，最终聚合物中有机硒基团的存在对生物相关应用尤其有价值。
A new versatile mediator for conducting “living” radical polymerization was developed based on diselenocarbonyl compounds. After the optimization of substitution groups, a “universal” diselenocarbonyl compound (O4) was developed and successfully applied to the controlled polymerization of both conjugated and unconjugated vinyl monomers, and the desired polymers with predetermined molecular weights and narrow molecular weight distributions were obtained in excellent yields. The characteristic feature of this method is exemplified by the synthesis of block copolymers composed of conjugated and unconjugated monomers, which would be of great importance as functional smart organic nanomaterials. Furthermore, the existence of organoselenium groups in the final polymers would be especially valuable for bio-related applications.
