The present invention provides unimolecular metal complexes having increased activity in the copolymerization of carbon dioxide and epoxides. Also provided are methods of using such metal complexes in the synthesis of polymers. According to one aspect, the present invention provides metal complexes comprising an activating species with co-catalytic activity tethered to a multidentate ligand that is coordinated to the active metal center of the complex.
本发明提供了在二氧化碳和环氧化物的共聚合中具有增强活性的单分子金属配合物。还提供了使用这种金属配合物在合成聚合物中的方法。根据一个方面,本发明提供了包括与具有共催化活性的活化物种相耦合的多齿配体的金属配合物,该多齿配体与复合物的活性金属中心配位。
