Computer calculation of isotopic effects in uranium-crown ether complexes

Structural Study of Mismatched Disila-Crown Ether Complexes

Mismatched complexes of the alkali metals cations Li+ and Na+ were synthesized from 1,2-disila[18]crown-6 (1 and 2) and of K+ from 1,2,4,5-tetrasila[18]crown-6 (4). In these alkali metal complexes, not all crown ether O atoms participate in the coordination, which depicts the coordination ability of the C-, Si/C-, and Si-bonded O atoms. Furthermore, the inverse case—the coordination of the larg...

Charge transfer in some complexes of crown ether and of thiacrown ether with dihalogens: DFT study.

The present study was carried out by focusing on the interaction between molecular complexes crown and thiacrown ethers such as 15-crown-5 (15C5), thia-15-crown-5 (T15C5), dithia-15-crown-5 (DT15C5) with homogeneous and heterogeneous dihalogens (XY) such as I2, IBr, ICl, Br2, Cl2 in the gas phase and in dichloromethane solvent through applying density function theory (DFT) as well as Gaussian 9...

Manganese(II)-lithium and -sodium inverse crown ether (ICE) complexes.

Extending to transition metals, the class of compounds known as inverse crown ethers, two mixed alkali metal-manganese(II) amide ring compounds with oxo cores have been synthesised and crystallographically characterised, together with an oxo-free alkyl-amido precursor.

Dithiolene complexes as metallo-ligands: a crown-ether approach

Electrochemiluminescence of ruthenium(II) complexes functionalized with crown ether pendants and effects of cation binding.

Electrochemiluminescence (ECL) of a series of ruthenium(II) diimine complexes with appended crown ethers derived from 1,10-phenanthroline was studied via either the annihilation route or the coreactant schemes, and the ECL efficiency has been determined. The effect of an FSN surfactant on the ECL properties was also studied in buffer solutions. The effect of cation binding on the ECL behavior w...
