Multifaceted aspects of charge transfer.
The fundamental concepts of charge transfer are reviewed, and its core role in a broad range of unrelated fields, such as medicine, environmental science, catalysis, electronics and photonics, are outlined.
Shortcuts for Electron-Transfer through the Secondary Structure of Helical Oligo-1,2-naphthylenes.
Atropisomeric 1,2-naphthylene scaffolds provide access to donor-acceptor compounds with helical oligomer-based bridges, and transient absorption studies reveal a highly unusual dependence of the
The Inverted Region in Bimolecular Electron Transfer in Solution Enabled by Delocalization.
Rate constants for bimolecular electron transfer increased with driving force, reached a plateau, and then decreased in an inverted region, implying that electronic couplings smaller than usually found for molecules in contact could boost efficiency of energy storage by electron transfer.
Bridge-Length- and Solvent-Dependent Charge Separation and Recombination Processes in Donor-Bridge-Acceptor Molecules.
The results imply that the VDA value is the key factor dominating the CS rate, while the facile rotation of the phenylene B is important for modulating the lifetime of the charge-separated state in these D-B-A dyads.
On the Determination of Halogen Atom Reduction Potentials with Photoredox Catalysts.
The use of two Ir(III) photoredox catalysts to initiate chloride, bromide, and iodide oxidation in organic solvents is reported and the origin(s) of such behavior are discussed that provide new directions for future research.
Resolving Halide Ion Stabilization through Kinetically Competitive Electron Transfers
Stabilization of ions and radicals often determines reaction kinetics and thermodynamics, but experimental determination of the stabilization magnitude remains difficult, especially when the species
Dynamic orientation control of bimolecular electron transfer at charged micelle surfaces.
Visible light excitation of the neutral complex [RuII(phen)2(bps)]0 (phen = 1,10-phenanthroline, bps = 4,7-biphenylsulfonate-1,10-phenanthroline) results in the formation of a triplet metal-to-ligand
Role of Explicit Hydration in Predicting the Aqueous Standard Reduction Potential of Sulfate Radical Anion by DFT and Insight into the Influence of pH on the Reduction Potential.
Sulfate radical anion (SO4•-) is a potent oxidant capable of destroying recalcitrant environmental contaminants such as perfluoroalkyl carboxylic acids. In addition, it is thought to participate in
Improved Visible Light Absorption of Potent Iridium(III) Photooxidants for Excited-State Electron Transfer Chemistry.
Three iridium photosensitizers, [Ir(dCF3ppy)2(N-N)]+, were found to be remarkably strong photo-oxidants with enhanced light absorption in the visible region and successful in performing light-driven charge separa-tion and energy storage.
