  Self-assembled mononuclear palladium(II) based molecular loops

  摘要：

  The meta-pyridine appended bidentate ligands L-1, L-2 and L-3, crafted with flexible polyether spacer, are prepared by condensation of nicotinoyl chloride hydrochloride with di, tri-, and tetra-ethyle ne glycol, respectively. Self-assembled palladium(II) based mononuclear molecular loops of general formula cis-[Pd(N-N)(L)](NO3)(2) are obtained exclusively by combining 1 equiv. of a ligand L with 1 equiv. of a cis-protected palladium(II) component, cis-[Pd(N-N)(NO3)(2)]. Complexation of 2 equiv. of L with 1 equiv. of palladium(II) nitrate also resulted mononuclear complexes, i.e. [Pd(L)(2)](NO3)(2). The ligands used in the complexation reactions are L-1, L-2 and L-3 where as the cis-protecting units N-N employed are ethylenediamine (en), 2,2'-bipyridine (bpy), and 1,10-phenanthroline(phen). Thus 12 number of mononuclear complexes are prepared using all possible combination of above mentioned three number of ligands and four variety of palladium(II) components. Large chelate rings are realized irrespective of the spacer length or type of palladium(II) component used. All the resulted compounds are characterized by NMR and ESI-MS techniques and the structure of cis-[Pd(en)(L-1)](NO3)(2), cis-[Pd(bpy)(L-1)](NO3)(2) and [Pd(L-3)(2)](NO3)(2) are confirmed by single crystal X-ray diffraction. The binding abilities of cis-[Pd(phen)(L-1)](NO3)(2), cis-[Pd(phen)(L-2)](NO3)(2) and cis-[Pd(phen)(L-3)](NO3)(2) with DNA has been investigated by ethidium bromide displacement assay and gel electrophoresis.

  Two types of molecular brakes based on two Zn–porphyrin units interconnected by a spacer are described. Their dynamic behaviour in solution at room temperature was studied by UV-Vis spectroscopy. In the absence of an external effector, the brake undergoes free rotation, whereas in the presence of an external effector, the rotational process may be hindered. The locking/unlocking processes are shown
