Abstract
The development of efficient catalysts for the catalytic conversion of CO 2 is extremely important in the process of CO 2 chemistry. In this work, a Zn-based coordination polymer (ZnBr 2 -CP) was synthesized from a tridentate pyridine ligand bearing an imidazolium salt ligated with ZnBr 2 . It possesses not only the high activity of homogeneous catalysts but also the recoverable features of heterogeneous catalysts. More importantly, configured double active sites allow the catalyst ZnBr 2 -CP to exhibit excellent activity in the cycloaddition of CO 2 with epoxides under solvent- and co-catalyst-free conditions, achieving yields as high as 99% for a variety of cyclic carbonates at 80 °C for 24 h. This study provides insight into the design of efficient catalysts for conversion of CO 2 .
