A layered covalent organic framework material based on an imine-linkage with high thermal and chemical stability was synthesized using a deep eutectic solvent as the green medium. The COF material was modified with catalytic copper, resulting in a crystalline and highly porous catalyst. This photocatalyst exhibited excellent photocatalytic performance in visible-light-driven coupling reactions and showed good recyclability.
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.
