A sustainable strategy for the visible-light-driven facile N-formylation of amines using a Co(ii)-embedded covalent organic framework as an efficient photocatalyst

We have constructed a highly crystalline 2D imine-linked Co( ii )-incorporated Tp-TH COF catalyst (Co( ii )@Tp-TH) with a band gap energy of 2.4 eV to serve as a stable and effective porous photocatalyst for the synthesis of N -formylated amines.
