Bacteria‐Triggered Solar Hydrogen Production via Platinum(II)‐Tethered Chalcogenoviologens

Multifunctional solar energy conversion offers a feasible strategy to solve energy, environmental and water crises. Herein, a series of platinum(II)‐tethered chalcogenoviologens (PtL+‐EV2+, E=S, Se, Te) is reported, which integrate the functions of photosensitizer, electron mediator and catalyst. Pt...

Description
Summary:Multifunctional solar energy conversion offers a feasible strategy to solve energy, environmental and water crises. Herein, a series of platinum(II)‐tethered chalcogenoviologens (PtL+‐EV2+, E=S, Se, Te) is reported, which integrate the functions of photosensitizer, electron mediator and catalyst. PtL+‐EV2+ (particularly for PtL+‐SeV2+)‐based one‐component solar H2 production could be triggered not only by EDTA, but also by facultative anaerobic and aerobic bacteria relying on a simplified mechanism, along with efficient antibacterial activities. In addition, by using real pool water, PtL+‐SeV2+ achieved multiple functions, including H2 production, antibacterial action and acid removal, which supplied a new strategy to solve various problems in real life via a single system. A series of platinum(II)‐tethered chalcogenoviologens with three‐in‐one functions was prepared. When bacteria were used as a natural sacrificial agent, PtL+‐SeV2+ could realize not only bacteria‐triggered one‐component solar H2 production but also antibacterial action. This system laid the foundation for solving various real‐life problems via a simple system.
