Abstract
Abstract Multifunctional solar energy conversion offers a feasible strategy to solve energy, environmental and water crises. Herein, a series of platinum(II)‐tethered chalcogenoviologens (PtL + ‐EV 2+ , E=S, Se, Te) is reported, which integrate the functions of photosensitizer, electron mediator and catalyst. PtL + ‐EV 2+ (particularly for PtL + ‐SeV 2+ )‐based one‐component solar H 2 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 + ‐SeV 2+ achieved multiple functions, including H 2 production, antibacterial action and acid removal, which supplied a new strategy to solve various problems in real life via a single system.
