A layered covalent organic framework (COF) material based on an imine-linkage with high thermal and chemical stability was prepared using a deep eutectic solvent (DES) as the green medium. The as-synthesized COF materials were modified with catalytic copper. This crystalline and highly porous catalyst shows excellent photocatalytic performance in visible-light-driven coupling reactions of terminal alkynes with H -phosphonates at room temperature. In addition, the photocatalyst could be recovered and recycled eight times without significant loss of its reactivity. A copper decorated covalent organic framework has been prepared and identified as an efficient heterogeneous photocatalyst for the phosphorylation of terminal alkynes.
