We have performed theoretical analyses of the photophysical properties of a series of cyclometalated gold(iii) arylacetylide complexes, [(C^N^C)AuIIIC 0000000000000000000000000000000000 0000000000000000000000000000000000 0000000000000000000000000000000000 0000000000000000000000000000000000 0000000000000000000000000000000000 0000000000000000000000000000000000 0000000000000000000000000000000000 0...

Oxidation-state-specific dynamics at the Fe M2,3-edge are measured on the sub-100 fs time scale using tabletop high-harmonic extreme ultraviolet spectroscopy. Transient absorption spectroscopy of α-Fe2O3 thin films after 400 nm excitation reveals distinct changes in the shape and position of the 3p → valence absorption peak at ∼57 eV due to a ligand-to-metal charge transfer from O to Fe. Semiem...

De novo metallopeptide design contributes significantly to the understanding of protein folding, protein–protein interactions, and metal-ion sites in biology. Within this rubric, studies in our research group have been focused on the biochemistry of Cd thiolate sites. A class of peptides based on the parent peptide TRI, Ac-G(LKALEEK)4G-NH2, was designed to assemble in aqueous solution into amph...

In a recent Letter published in this journal, Willig et al. reported on the ultrafast electron transfer from photoexcited ruthenium(II) cis-di(isothiocyanato)bis(4,4′-dicarboxy-2,2′-bipyridyl),1 (N3), into titania. This dye has attracted wide attention as a highly efficient charge-transfer sensitizer for mesoporous TiO2 films.2 A key element of Willig et al.’s results was the determination of t...

Superoxide reductases (SORs) belong to a new class of metalloenzymes that degrade superoxide by reducing it to hydrogen peroxide. These enzymes contain a catalytic iron site that cycles between the FeII and FeIII states during catalysis. A key step in the reduction of superoxide has been suggested to involve HO2 binding to FeII, followed by innersphere electron transfer to afford an FeIII-OO(H)...
