A nitrogen‐phenyl‐bridged copper porphyrin polymer was synthesized, and copper ions were further coordinated on the bridging imine groups to obtain a copper porphyrin polymer containing two coordinative copper ions (Cu–MP−Cu‐2). The polymer was characterized by IR, SEM/TEM, N 2 adsorption and XPS. Cu–MP−Cu‐2 has an unequal columnar structure accumulated by porphyrin layers with diameters of about 20–100 nm. Cu–MP−Cu‐2 also has an excellent micro‐mesoporous structure on the surface and in the interior. Under the synergistic catalysis of imino‐coordinated Cu(II) and Cu(II) in the porphyrin ring, the polymer can catalyze the oxidative coupling of alcohols and acetonitrile to form β‐ketonitrile compounds with high efficiency because of its special structure. The Cu–MP−Cu‐2 remained stable and still had high catalytic activity after several recycles.
