Extended π-Conjugation in Ni-Phenanthroline Covalent Organic Cages Prolongs Charge Lifetime for Efficient Photocatalytic CO2 Reduction.
The local microenvironment of metal centers critically dictates the activity and selectivity in photocatalytic CO2 reduction. Herein, we report two isoreticular covalent organic cages, Ni-PHEN and Ni-BPY, featuring Ni(II) coordinated by phenanthroline and bipyridine motifs, respectively. The Ni-PHEN cage exhibits marke...
