Toward luminescence vapochromism of tetranuclear AuI-Cu I clusters
A family of triphosphine gold–copper clusters bearing aliphatic and hydroxyaliphatic alkynyl ligands of general formula [HC(PPh2)3Au3Cu(C2R)3]+ (R = cyclohexyl (1), cyclopentyl (2), But (3), cyclohexanolyl (4), cyclopentanolyl (5), 2,6-dimethylheptanolyl (6), 2-methylbutanolyl (7), diphenylmethanolyl (8)) was synthesized via a self-assembly protocol, which involves treatment of the (AuC2R)n acetylides with the (PPh2)3CH ligand in the presence of Cu+ ions and NEt3. Addition of Cl– or Br– anions to complex 8 results in coordination of the halides to the copper atoms to give neutral HC(PPh2)3Au3CuHal(C2COHPh2)3 derivatives (Hal = Cl (9), Br (10)). The title compounds were characterized by NMR …
Metallophilicity-assisted assembly of phosphine-based cage molecules.
A family of supramolecular cage molecules has been obtained via self-assembly of the phosphine-gold coordination complexes following an aurophilicity-driven aggregation approach. Use of the di- (PP) or tridentate (PPP) phosphine ligands Pn (n = 2, 3) with rigid polyaromatic backbones leads to clean formation of the coordination Pn(Au(tht))n(n+) species, sequential treatment of which with H2O/NEt3 and excess of H2NBu(t) gives the finite 3D structures of two major types. The cylindrical-like hexametallic cages [(PPAu2)3(μ3-NBu(t))2](2+) are based on the diphosphines PP = 1,4-bis(diphenylphosphino)benzene (1), 4,4'-bis(diphenylphosphino)biphenyl (2), 4,4"-bis(diphenylphosphino)terphenyl (3), w…
