Sn(IV) porphyrins are an excellent choice as scaffolds for the construction of multiporphyrin assemblies because of their preferential coordination for oxygen donor ligands. The remarkable affinity of Sn(IV) porphyrins toward carboxylates and aryloxides combined with the complementary preferential binding of nitrogen based ligands by Zn(II), Ru(II) and Rh(III) porphyrins were used in the construction of several elegant and elaborate multiporphyrin assemblies. Sn(IV) porphyrins possess very interesting photophysical and electrochemical properties. Sn(IV) porphyrins are diamagnetic with NMR active Sn(IV) nucleus, allowing one to obtain detail structural information of Sn(IV) porphyrin based multiporphyrin assemblies. This article presents a brief overview of the synthesis and properties of Sn(IV) porphyrin based multiporphyrin assemblies reported in the last decade.
