Helicates as Versatile Supramolecular Complexes.

Spontaneous resolution of silver double helicates consisting of achiral ligands with several aromatic rings.

Symmetric breaking of silver double helicates through spontaneous crystallization was achieved via incorporation of C-H...pi and pi-pi stacking interactions of achiral ligands consisting of several aromatic rings.

Metal Complexes with Biologically Important Ligands, XXXIX [1] Platinum(IV) Complexes with a-Amino Acid Esters and Peptide Esters;

a-Amino Acid Esters, Peptide Esters, Platinum(IV) Complexes, "N NMR Spectra, Pt NMR Spectra The platinum(IV) complexes PtX4L2 (X = Cl, Br; 2 X = oxalate; L = glyOEt, glyglyOEt, gly-cleuOEt; 2 L = metOEt) have been obtained by oxidative addition of halogenes to platinum(II) compounds PtX2L2A high field shift of <3N (—50 ppm) is observed for the coordinated amino acid ligand of various platinum c...

Luminescent lanthanide helicates self-assembled from ditopic ligands bearing phosphonic acid or phosphoester units.

A series of hexadentate ditopic receptors incorporating benzimidazole moieties have been designed, which are fitted with phosphonic acid or phosphoethylester coordinating units. In addition, poly(oxyethylene) pendants have been introduced on the benzimidazole backbone of two ligands to increase water solubility. The ligands self-assemble with lanthanide ions under stoichiometric conditions, yie...
