Abstract

Abstract : Through chemical design, an asymmetric bis-β-diketonate ligand has been prepared and engineered to form triple-stranded dinuclear supramolecular helicates, exhibiting structural asymmetry. Abstract : A new bis-(β-diketone) ligand featuring built-up structural asymmetry yields non-symmetric Fe(iii ) and Ga(iii ) dinuclear, triple-stranded helicates by design. Their structural properties have been studied, both in solid state and in solution, and compared with their corresponding symmetric analogues. The robustness observed shows the potential of this synthetic strategy to develop non-symmetric helicoidal motifs with specific functional groups.
