Summary

The urgent need for alternative fuel sources has stimulated research in solar hydrogen production. Photoinitiated electron collection is applicable in solar hydrogen production and uses light to collect reducing equivalents. Solar hydrogen production from water using mixed-metal supramolecular complexes through photoinitiated electron collection is summarized. Many successful systems couple multiple polyazine light absorber units that are electronically isolated to a single reactive metal. Upon optical excitation, these systems collect and deliver multiple electrons to substrates, such as water, producing hydrogen. The design considerations for a functioning system for light activated multi-electron reduction of water to produce hydrogen are described.
