"2 orders magnitude (100 times) longer, giving catalyst more time to diffuse/ encounter another molecule with which to transfer an electron, enabling photoreaction... single-step reaction directly from commercially available colorless: manganese salt and a ligand... resulting in deep purple complex exhibiting strong light absorption... sustainable, highly efficient, robust behavior, long excited-state lifetime... large-scale photoreaction applications, such as sustainable hydrogen production"
