Light‐Activated Antibacterial Nanoscale Films: Metallo‐Organics for Catalytic Generation of Chemically Accessible Singlet‐Oxygen in Water

Abstract

We demonstrated a heterogeneous and efficient photocatalytic method to reduce the bacterial content in water with reusable metallo‐organic thin films. These functionalized assemblies constructed of a network of polypyridyl complexes generate reactive singlet oxygen upon visible light irradiation that induces lysis of bacterial cells. The singlet oxygen photosensitizers are robust and were successfully applied to surface water samples contaminated with both Gram‐positive and ‐negative bacteria. The catalytic formation of singlet oxygen by our antibacterial coatings was confirmed chemically by reactions with both inorganic and organic compounds.

Dual Function Metallo–Organic Assemblies for Electrochromic–Hybrid Supercapacitors

“…[ 11,26 ] Metallo–organic assemblies have also been studied by us and others for their electron‐transport properties, Boolean logic operations, organic photovoltaics, sensing, and use as antibacterial coatings. [ 44–48 ] The current work indicates that such dual‐functional materials are promising candidates as charge‐indicators. It is foreseeable that such assemblies can be integrated in elastic and stretchable polymers to fabricate electrochromic–hybrid supercapacitors.…”
