Two new chiral calix[4] arene-salen ligands 1a,b, based on calix[4] arene platforms in 1,3-alternate conformation, have been prepared by a new general synthetic pathway. Their Mn(III) complexes, 3a,b, have shown fairly good efficiency in the asymmetr

A new series of supramolecular assemblies is obtained through the interaction of 3-pyridylmethyl-calixarenes and copper or zinc ions. The complexes formed are characterized both in solution and in the solid state. The results offer appealing insights

Two calix[4]arene receptors containing two or four 3-pyridylmethyl pendants at the lower rim and fixed in the cone conformation have been synthesised. Their complexes with Cu2+ and Zn2+ have been studied via UV-vis absorption spectroscopy in acetonit

Two dipyridyl pendants were attached to the 1,3 positions of a calix[4]arene, with the purpose of having a ligand able to complex Cu(II) and Co(II). Indeed, the new ligand, fixed in its 1,3-alternate conformation, forms stable complexes with both Co(
