This designed molecular architecture is a supramolecular complex design capable of converting radiant energy to chemical energy in the form of hydrogen. This novel system includes a vessel, containing water and the supramolecular complex, to produce hydrogen from the water using solar light. The supramolecular complexes absorb visible light and undergo charge transfer. By design, this charge transfer leads to the collection of electrons at a reactive metal center. Once these electrons have been photochemically collected, they are used to reduce water to hydrogen. This invention covers one half of a solar water splitting scheme, and is considered to be the fuel production side. These supramolecular complexes are easily coupled with current oxidizers to complete the solar water splitting cycle, procing hydrogen and oxygen.
