A stable microporous mixed-metal metal-organic framework with highly active Cu2+ sites for efficient cross-dehydrogenative coupling reactions.
Two metalloporphyrin octacarboxylates were used to link copper(II) nodes for the formation of two novel porous mixed-metal metal-organic frameworks (M'MOFs) containing nanopore cages (2.1 nm in diameter) or nanotubular channels (1.5 nm in diameter). The highly active Cu(2+) sites on the nanotubular surfaces of the stable porous M'MOF ZJU-22, stabilized by three-connected nets, lead to the superior catalytic activity for the cross-dehydrogenative coupling (CDC) reaction.
