Polaritons are an odd cross-breed of a particle, half-matter, half-light. They could offer an abundant crop of new and improved optoelectronic devices — a promise already being fulfilled. ...
Hydrophilic/hydrophobic patterning is a powerful strategy to control folding in non-natural polymers/oligomers. In this contribution, we present a novel strategy for the preparation of alternating hydrophilic/hydrophobic patterned non-natural peptide folda ...
The synthesis of the first π-extended tetrathiafulvalene (TTF) ligand featuring a furanoquinonoid spacer and pyridyl functional groups is described. This compound shows an unprecedented electrochemical sensing behavior and excellent coordinating properties ...
Conformational transitions have found broad interest due to their impact on protein misfolding and self-assembly as key events leading to the development of neurodegenerative diseases. However, investigation of these dynamic events has been limited so far ...
The reaction of [(η6-p-cymene)RuCl2]2 with some bis(phosphane) ligands (dppm, dppe, dppv, dppa, dpp14b, dppf) has been investigated. In general mixtures of products were obtained, although the pendant phosphane complexes [( ...
Reaction of 1,1'-bis(diphenylphosphino)binaphthol (BINAPO, 1) with [RuCl2(η6-arene)]2 in methanol leads to dinuclear BINAPO-bridged Ru compounds [{RuCl2(η6-p-cymene)}2-(μ-BINAPO)], 2a, in ne ...
The triple-chlorido-bridged heterodimetallic dinuclear complex [(dibenzo-18-crown-6)K(m-Cl)3Ru(h6-p-cymene)] contg. an (h6-arene)RuII fragment and a Group 1 metal crown ether fragment was synthesized and characterized by spectroscopy and X-ray crystallog. ...
The two known Me- and allyl-substituted 1H-imidazol-3-ium bromides 1 and 2, respectively, were converted to the corresponding BF4- and BPh4- salts 3-6 (Scheme 1). Compounds 3 and 4 were liquids at ambient temperature. Reaction of 1 or 2 with [PdCl2] afford ...
Incorporation of a nitrogen functionality into a tripodal N-heterocyclic carbene ligand system affords the first N-anchored tetradentate tris-carbene ligands TIMENR I (R = Me (5a), t-Bu (5b), Bz (5c)). Treatment of the Me derivatized H3TIMENMe3 imid ...
We discuss a method for determining the optimally localized set of generalized Wannier functions associated with a set of Bloch bands in a crystalline solid. By ''generalized Wannier functions'' we mean a set of localized orthonormal orbitals spanning the ...
