Study of the self-assembly reactions between the organic linker 1,4-bis(4-pyridyl)butadiyne and the metal-containing corners (diphosphine)M(II) (M=Pd, Pt; diphosphine=dppp, dppf, depe, dppbz)
摘要:
The diaza ligand 1,4-bis(4-pyridyl)butadiyne (L) has been used as a linker in self-assembly reactions with different diphosphine Pd(II) and Pt(II) triflates to build metallosupramolecular squares and triangles. Equilibria between triangular and square entities have been detected in most of the cases and their composition studied by multinuclear NMR spectroscopy and mass spectrometry. The self-assembly process has been shown to be strongly dependent on the conditions of the medium and the nature of the transition metal. The ability of some of these compounds to recognise inorganic anions has been investigated. (C) 2003 Elsevier B.V. All rights reserved.
