2005 (English)In: Coordination chemistry reviews, ISSN 0010-8545, E-ISSN 1873-3840, Vol. 249, no 15-16, 1653-1663 p.Article, review/survey (Refereed) Published
Models of the iron hydrogenase active site [(mu-DT)Fe-2(CO)(6)] (DT: dithiolate) have been synthesized where the dithiolate co-factor bears a functional group to allow for their incorporation into supramolecular systems. Covalently linked to ruthenium(II) polypyridyl photosensitizers, the resulting ruthenium-diiron complexes represent the first members of a new class of dyads designed to promote the light-driven production of hydrogen. The functionalized diiron complexes have been characterized by X-ray crystallography. The redox properties of all complexes were investigated by cyclic voltammetry and the interactions between the photo-excited ruthenium moiety and the diiron unit in these dyads were evaluated by time-resolved spectroscopy.
