Well-defined coinage metal transfer agents for the synthesis of NHC-based nickel, rhodium and palladium macrocycles†
With a view to use as carbene transfer agents, well-defined silver(I) and copper(I) complexes of a macrocyclic NHC-based pincer ligand, bearing a central lutidine donor and a dodecamethylene spacer [CNC– (CH2)12, 1], have been prepared. Although the silver adduct is characterised by X-ray diffraction as a dinuclear species anti-[Ag(μ-1)]2, variable temperature measurements indicate dynamic stru...
متن کاملSynthesis and Characterization of Homo and Heterobimetallic Complexes with a Dicompartmental Macrocyclic Ligand Containing Propionitrile Pendent Arms
A binuclear macrocyclic ligand containing dissimilar N(amine)2O2 and N(imine)2O2 coordination sites sharing two phenolic oxygen atoms, was prepared by cyclic condensation of dialdehyde precursor L1H2 with 1,3-diaminopropane. The ligand includes two propionitrile pendant arms on the amine nitrogen atoms. The homobimetallic com...
متن کاملReversible luminescent colour changes of mononuclear copper(i) complexes based on ligand exchange reactions by N-heteroaromatic vapours.
[CuCl(PPh3)2(4-Mepy)] (PPh3 = triphenylphosphine, 4-Mepy = 4-methylpyridine), a highly blue-luminescent mononuclear copper(i) complex, shows reversible emission colour change ranging from blue-green to red by vapour exposure to N-heteroaromatics, such as pyridine, pyrimidine, and 2-methylpyrazine. The remarkable colour changes occur due the ligand exchange reaction between the solid and gas. Su...
متن کاملBinuclear Complex of Zinc and Copper with Unsymmetrical Macrocyclic Ligand as Sensitizer in Nanocrystaline TiO2 Solar Cells
Dye sensitized solar cells (DSSCs) are considered as one of the most promising alternativerenewable energy sources. In the structure of DSSCs, a photosensitizer composed of transitionmetal complexes is used to harvest light. In this work a binuclear complex containing twopropionitrile pendant arms [ZnLCu(OAC)]PF6 {L = 1, 6- bis (2-cyanoethyl) -2, 5-bis (2-hydroxy3-formyl-5-methylbenzyl)-2, 5- d...
متن کاملCopper(II) and triphenylphosphine copper(I) ethylene glycol carboxylates: synthesis, characterisation and copper nanoparticle generation.
Ethylene glycol-functionalised copper(II) carboxylates Cu[O2CCR2(OC2H4)nOCH3]2 (n = 0-3; R = H, Me) (2a-e) have been prepared by the reaction of [Cu2(OAc)4·2H2O] with CH3O(C2H4O)nCR2CO2H (1a-e). Upon reduction of 2a-e with triphenylphosphine, the corresponding tris(triphenylphosphine)copper(I) complexes 3a-e were obtained, which could be converted to the bis(triphenylphosphine)copper(I) complex...
