Completing a Charge Transport Chain for Artificial Photosynthesis

Oxidative equvalents are transiently stored on a triarylamine following photoexcitation of a ruthenium polypyridyl chromophore and electron injection to a TiO₂ electrode. Electron injection is rate limiting with k = 10¹⁰ s^-1 followed by rapid electron transfer from the pendant triarylamine to Ru(III).

Water Photo-oxidation with Organic Chromophores

Organic photosensitizers are frequently unstable upon oxidation under aqueous conditions, however a series of simple triphenylamine dyes show much better redox stability and redox potentials that are sufficient for water oxidation chemistry.

Electron Transfer from Hexameric Copper Hydrides

Copper hydrides are strong reducing agents with redox potentials as strong as cobaltocene and maintain their hexameric structure in solution. The six hydride ligands undergo rapid intramolecular exchange over the eight faces of the roughly octahedral copper cluster
