The Role of Site-Specific Hydrogen Bonding Interactions in the Solvation Dynamics of N-Acetyltryptophanamide

Majed Chergui, Ahmed Maher Fahmy El-Zohry

Measurements of the ultrafast broadband UV fluorescence of N-acetyltryptophanamide (NATA) provide detailed information on its relaxation patterns in three different solvents: methanol (MeOH), water and acetonitrile (ACN). Several processes leading to excit ...

Bonding and Charge Transfer in Metal-Organic Coordination Networks on Au(111) with Strong Acceptor Molecules

Klaus Kern, Sebastian Stepanow, Alexander Langner, Nan Jiang

The geometric and electronic structure of two structurally similar metal organic networks grown on the Au(111) surface is investigated by scanning tunnelling microscopy (STM) and spectroscopy (STS) combined with density functional theory (DFT) calculations ...

Mn2+ Complexes with 12-Membered Pyridine Based Macrocycles Bearing Carboxylate or Phosphonate Pendant Arm: Crystallographic, Thermodynamic, Kinetic, Redox, and 1H/17O Relaxation Studies

Lothar Helm, Eva Jakab Toth

Mn2+ complexes represent an alternative to Gd3+ chelates which are widely used contrast agents in magnetic resonance imaging. In this perspective, the authors studied the Mn2+ complexes of two 12-membered, pyridine-contg. macrocyclic ligands bearing one pe ...

Hierarchical Assembly and Reticulation of Two-Dimensional Mn- and Ni-TCNQ(x) (x=1, 2,4) Coordination Structures on a Metal Surface

Klaus Kern, Sebastian Stepanow, Tzu-Chun Tseng, Nasiba Abdurakhmanova

We report a scanning tunneling microscopy (STM) investigation of the self-assembly of two-dimensional metal-organic coordination networks comprised of Mn or Ni atoms (M) and 7,7,8,8-tetracyanoquinodimethane (TCNQ) molecules on a Ag(100) surface. The growth ...

Crystal and Electronic Structures of Magnesium(II), Copper(II), and Mixed Magnesium(II)−Copper(II) Complexes of the Quinoline Half of Styrylquinoline-Type HIV-1 Integrase Inhibitors

Philip Pattison

A new target in AIDS therapy development is HIV-1 integrase (IN). It was proven that HIV-1 IN required divalent metal cations to achieve phosphodiester bond cleavage of DNA. Accordingly, all newly investigated potent IN inhibitors contain chemical fragment ...

New tripodal N-heterocyclic carbene chelators for small molecule activation

Xile Hu

A review. In an effort to develop new tripodal N-heterocyclic carbene (NHC) ligands for small mol. activation, two new classes of tripodal NHC ligands TIMER and TIMENR were synthesized. The C-anchored tris(carbene) ligand system TIMER (R = Me, t-Bu) forms ...

Diastereoselective formation of metallamacrocyclic (arene)Ru-II and Cp*Rh-III complexes

Kay Severin

The reaction of (arene)RuCl2 (arene = cymene, 1,3,5-C6H3Me3) and Cp*RhCl2 half-sandwich complexes with tridentate heterocyclic ligands in the presence of base has been investigated. In all cases, the chloro-ligands were substituted to give metall ...
