在这里，我们报告了pnp -钳形铱(I)配合物在DMF/水中定量电还原CO2为CO。电催化性能在很大程度上取决于配体内连接体的选择。3-N配合物远优于亚甲基和氧连接的类似物，对CO2比质子还原具有更高的活性和更好的选择性。
Here, we report the quantitative electroreduction of CO2 to CO by a PNP-pincer iridium(I) complex bearing amino linkers in DMF/water. The electrocatalytic properties greatly depend on the choice of linker within the ligand. The complex 3-N is far superior to the analogues with methylene and oxygen linkers, showing higher activity and better selectivity for CO2 over proton reduction.
