Outer-sphere anion recognition by a cyclen-based octadentate europium(III) complex: pH dependent recognition of ortho-phthalic acid.
An octadentate cyclen-based europium complex with amidic and hydroxyalkyl pendent moieties exhibits pH dependent ligand denticity associated with anion recognition. Unusually high hydration numbers are determined for ortho-phthalate ternary outer-sphere complexes for which modulation of lanthanide-based luminescence is observed.
متن کاملNi(O2) complex by anion photoelectron spectroscopy
We report the first anion photoelectron spectroscopic study of nickel monoxide ~NiO!, nickel dioxide ~ONiO!, and nickel-O2 complex, Ni~O2!. The adiabatic electron affinity ~EA! of NiO is measured to be 1.46 ~2! eV. Five low-lying electronic excited states (A P , a D , B F , b S, c P) are observed for NiO at 0.43 ~4!, 0.94 ~4!, 1.24 ~3!, 1.80 ~10!, and 2.38 ~10! eV above the ground state, respec...
متن کاملPhosphate binding by a novel Zn(II) complex featuring a trans-1,2-diaminocyclohexane ligand. Effective anion recognition in water.
In this work we have investigated the binding properties of a new synthetic receptor for phosphate anions that combines metal ion coordination with electrostatic and H-bonding interactions. The described receptor is obtained by assembling an iminodiacetic (IDA) fragment, as a Zn(II) binding site, with a polyamine macrocyclic portion containing two trans-1,2-diaminocyclohexane (DAC) units and a ...
متن کاملAnion Recognition and Selectivity by a Thiophene Based Cryptand
Anion recognition and sensing is one of the most emerging areas in supramolecular chemistry. Because of the adverse effect of some anions on health, this area is gaining considerable interest to the researchers. In particular, polyammonium hosts have been known to interact strongly a variety of anions in water. During our study, a thiophene based polyazabicyclic compound has been synthesized an...
متن کاملSulfate anion stabilization of native ribonuclease A both by anion binding and by the Hofmeister effect.
Data are reported for T(m), the temperature midpoint of the thermal unfolding curve, of ribonuclease A, versus pH (range 2-9) and salt concentration (range 0-1 M) for two salts, Na(2)SO(4) and NaCl. The results show stabilization by sulfate via anion-specific binding in the concentration range 0-0.1 M and via the Hofmeister effect in the concentration range 0.1-1.0 M. The increase in T(m) cause...
