Multicomponent coordination‐driven self‐assembly has proved to be a convenient approach to prepare advanced supramolecular coordination complexes (SCCs), especially for those with three‐dimensional structures. Herein, we report the preparation of three tetragonal prismatic cages via the self‐assembly of Pt(PEt 3 ) 2 (OTf) 2 , three different linear dipyridyl ligands and porphyrin‐based sodium benzoate ligands. Due to the efficient charge separation in the coordination process of Pt(PEt 3 ) 2 (OTf) 2 with pyridine and carboxylic acid and the directionality of metal‐coordination bonds, these cages were prepared in high isolated yields (more than 90 %). The absorption and emission properties as well as the singlet oxygen quantum yields of these cages were also studied, showing their potential applications as contrast agents for bio‐imaging and photosensitizers for photodynamic therapy.
