Photocatalytic water splitting is a clean and renewable technology to produce hydrogen through solar energy conversion schemes. Mixed-metal supramolecular complexes provide promising structural motifs for solar energy conversions. We recently reported a mixed-metal supramolecular complex [{(bpy)2Ru(dpp)}2RhCl2}]5+ which has the ability to photochemically collect reducing equivalents on a metal center (Inorg. Chem. 2006, 45, 5242). This complex can photocatalyze the production of hydrogen from water. Studies directed towards understanding the photocatalytic activity of the supramolecular complex in more detail and component modification to optimize solar hydrogen production from water will be described. The application of high throughput Light Emitting Diode (LED) arrays aids in the analysis of this system.
