Title: Octahedral Molybdenum Cluster Complexes for Photodynamic Applications

Summary:

Octahedral molybdenum clusters are nanometer-sized metallic aggregates stabilized by eight
strongly bonded halogen (Cl, Br, I) inner ligands and six apical ligands of inorganic or organic
nature. When irradiated by UV, visible light or even X-rays, the resulting complexes form longlived
triplet states that relax via a red-NIR phosphorescence or by energy transfer to molecular
oxygen, forming the cytotoxic singlet oxygen with high quantum yields. Herein, recent
developments regarding the design of octahedral molybdenum cluster complexes towards
photodynamic therapy or photoinactivation of bacteria will be summarized.
