The metal complex formation and the electrical properties of amorphous solid polymer electrolytes, based on poly(butadiene–acrylonitrile) copolymer (PBAN) and CoCl2, have been studied over the homogeneity region of the system limited by the CoCl2 concentration of 1.89 mol kg−1. It has been...

N-carboxyethylation of chitosan by b-halopropionic acids in the presence of various proton and halogen ion acceptors was investigated. It has been observed that carboxyethylation of chitosan in aqueous medium is accompanied by the by-processes of hydrolysis and dehydrohalogenation of the...

Recent studies on metal incorporation in ligand-modified nucleic acids have focused on the effect of metal coordination on the stability of metal-containing duplexes or triplexes and on the metal binding selectivity but did not address the effect of the sequence of the nucleic acid in which the...

The copper(II) complex formation equilibria of N-(2-carboxyethyl)chitosans with three different degrees of substitution (DS ) 0.42, 0.92, and 1.61) were studied in aqueous solution by pH-potentiometric and UVspectrophotometric techniques. It was demonstrated that the complexation model of...

The CuII ion in the title complex, [Cu(C5H10NO3)2] or [Cu(He-ala)2] (He-ala = N-(2–Hydroxyethyl)- -alaninate), resides at the inversion center of a square bipyramid comprised of two facially arranged tridentate He-ala ligands. Each He-ala ligand binds to a CuII by forming one six-membered...
