Abstract

Two novel polyoxovanadate-iodoBodipy supramolecular assemblies, named as (2I-BDP-C₆)₂V₆ and (2I-BDP-C₆)₃V₁₀, were first synthesized by self-assembly of anionic hexavanadate and decavanadate with cationic iodoBodipy for photochemotherapy, respectively. The mechanisms for synergistic photochemotherapy of anion-cation pairs were forced on. In particular, (2I-BDP-C₆)₃V₁₀ is the first example of polyoxovanadates used for photochemotherapy which can effectively kill lung cancer cells (HepG2) by synergetic chemotherapy as well as photodynamic therapy.
