A new hydrophilic supramolecular photocatalyst for the production of H2 in aerobic aqueous solutions†
Abstract
Addition of sulfonated terminal ligands into a Ru,Rh,Ru photocatalyst has a significant impact on the excited-state properties of the complex. The hydrophilic photocatalyst demonstrates increased solubility and H2 production in aqueous solutions. H2 production is observed under aerobic conditions for the new complex, a stark contrast to the hydrophobic analog in organic solvents.
