ABSTRACT=<p>In recent years, metal coordination macrocycles have obtained great interests due to the fact that they combined the rich host-guest properties of macro-cyclic hosts and the unique optical properties of the organic ligands. In this work, we constructed two porphyrin-based organoplatinum(II) metallacycles (<bold>MC1</bold> and <bold>MC2</bold>) through coordination-driven self-assembly. <sup>1</sup>H NMR, <sup>31</sup>P NMR, and HRMS technologies were used to characterize the structures of <bold>MC1</bold> and <bold>MC2</bold>. Interestingly, <bold>MC1</bold> and <bold>MC2</bold> can be used as catalysts for photooxidization under light irradiation with higher efficiency compared with the porphyrin ligand only. We hope that the coordination-driven self-assembly strategy can provide an efficient method to construct photo-active materials.</p>
