Solar energy is a very attractive alternative for the production of carbon-neutral fuels such as hydrogen gas in a renewable fashion. There are many examples of chromophore-catalyst assemblies for photocatalytic hydrogen production, but these systems have several drawbacks. For example, ruthenium(II) complexes have been extensively used for these purposes, but they are unable to significantly absorb light beyond 600 nm. This situation limits the efficiency of these chromophore-catalyst assemblies due to the fact that they cannot make use of the full solar spectrum. Axially blocked dirhodium complexes, on the other hand, have been shown to be panchromatic light absorbers which render them excellent candidates for these applications. In addition, axially available dirhodium complexes are known to catalyze a large number of reactions. With these considerations in mind, the synthesis, characterization, and low energy light induced photocatalytic hydrogen production capabilities of a new class of asymmetric dirhodium complexes will be presented.
