Unprecedented detection of inherent chirality in uranyl-salophen complexes.
In complexes with the uranyl dication salophen ligands are highly puckered. This implies that non-symmetrically substituted uranyl-salophen derivatives exist in principle as a pair of enantiomers. However, due to easy disrotations about the bonds connecting the phenoxide units to the imine carbons, the rate of interconversion between enantiomeric forms of simple, sterically unhindered compounds...
متن کاملCatalysis: transition-state molecular recognition?
THE KEY TO UNDERSTANDING THE FUNDAMENTAL PROCESSES OF CATALYSIS IS THE TRANSITION STATE (TS): indeed, catalysis is a transition-state molecular recognition event. Practical objectives, such as the design of TS analogues as potential drugs, or the design of synthetic catalysts (including catalytic antibodies), require prior knowledge of the TS structure to be mimicked. Examples, both old and new...
متن کاملX-Ray crystallographic and computational study on uranyl-salophen complexes bearing nitro groups.
In the solid state, salophen-UO2 complexes bearing one, two, or three NO2 groups lack the pronounced ligand curvature that represents a structural hallmark for this class of compounds. A detailed structural study based on single-crystal X-ray crystallography and computational methods, comprising molecular dynamics, gas-phase Hartree Fock, and DFT calculations, was carried out to investigate the...
متن کاملExcited State Behavior of Uranyl Complexes with Salophen and Oxine as Chromophoric Ligands
The electronic spectra and the photochemistry of the uranyl complexes UO2 (salophen) and UO2 (oxinate)2 with H2salophen = N,N'-bis(salicylidene)-o-phenylenediamine and oxine = 8hydroxyquinoline were studied. The excited state behavior of both complexes is determined by a low-energy salophen / oxinateÿ to U(VI) ligand-to-metal charge transfer (LMCT) state which is not luminescent but can be reac...
