Based on the 5,10,15,20-tetra(cyanophenyl)porphyrin (CNTCPP) ligand, two supermolecule complexes formulated as [Cu(CNTCPP)]·2DMF (Cu-CNTCPP) and [Zn(CNTCPP)] (Zn-CNTCPP) have been synthesized and structurally characterized by single-crystal X-ray diffraction. Cu-CNTCPP features a 0 dimensional (0D) supramoleculer structure, whereas Zn-CNTCPP is a 2D structure. With coordination unsaturated points, Cu-CNTCPP exhibits electrocatalytic activity toward oxygen evolution reaction (OER) with low potential in 1.0 M KOH, generating a current density of 10 mA cm at an potential of 1.66 V RHE, which means it an efficient electrocatalytic material for OER.
基于5,10,15,20-四（氰基苯基）卟啉（CNTCPP）配体，已合成了两种超分子配合物，其化学式分别为[Cu(CNTCPP)]·2DMF（Cu-CNTCPP）和[Zn(CNTCPP)]（Zn-CNTCPP），并通过单晶X射线衍射对其结构进行了表征。Cu-CNTCPP具有零维（0D）超分子结构，而Zn-CNTCPP是二维结构。由于具有配位不饱和点，Cu-CNTCPP在1.0 M KOH中对析氧反应（OER）表现出低电位的电催化活性，在1.66 V RHE的电位下产生10 mA cm的电流密度，这意味着它是一种用于OER的高效电催化材料。
