Coordination singularities of a bis(p-xylyl)bis(benzimidazolylidene) ligand and the bis-iridium and -rhodium-related complexes
American Chemical Society (2013)The reaction of bis(α,α′-p-xylyl)bis(benzimidazolium) dichloride with [IrCpCl2]2 or [RhCl(COD)]2 affords the corresponding dimetallic bis-N-heterocyclic carbene complexes of Ir and Rh. The reaction with the iridium complex ... -
Development of efficient processes under flow conditions based on catalysts immobilized onto monolithic supported ionic liquid-like phases
International Union of Pure and Applied Chemistry (2009)The introduction of imidazolium subunits into polystyrene-divinylbenzene (PS-DVB) polymers enables the preparation of a variety of catalytic systems. Those include the stabilization of catalytically active Pd nanoparticles ... -
First-passage-time analysis of atomic-resolution simulations of the ionic transport in a bacterial porin
American Physical Society (2011-02-16)We have studied the dynamics of chloride and potassium ions in the interior of the Outer membrane porin F (OmpF) under the influence of an external electric field. From the results of extensive all-atom molecular dynamics ... -
Pseudopeptidic Cages as Receptors for N-Protected Dipeptides
American Chemical Society (2014-04)The molecular recognition of short peptides is a challenge in supramolecular chemistry, and the use of peptide-like cage receptors represents a promising approach. Here we report the synthesis and characterization of a ... -
Selectivity of Protein Ion Channels and the Role of Buried Charges. Analytical Solutions, Numerical Calculations, and MD Simulations
American Chemical Society (2015-06)The preference of large protein ion channels for cations or anions is mainly determined by the electrostatic interactions of mobile ions with charged residues of the protein. Here we discuss the widely spread paradigm that ... -
The Role of the Amino Acid Derived Side Chain in the Preorganization of C2 Symmetric Pseudopeptides: Effect on SN2 Macrocyclization Reactions
American Chemical Society (2013-12)A family of pseudopeptidic macrocycles containing non-natural amino acids have been synthesized. The macrocyclization reaction has been studied experimentally and computationally, demonstrating the key role of both the ... -
Tripodal halogen bonding iodo-azolium receptors for anion recognition
Royal Society of Chemistry (2017)The synthesis, characterization and anion binding properties of 1,3,5-tri-substituted benzene platform-based tripodal receptors containing halogen bonding (XB) iodo-imidazolium and iodo-triazolium motifs, and hydrogen ...
