  Homoleptic ligands vs heteroleptic ligands on coordination polymerizations: Construction and properties of silver(I) coordination polymers containing dialkylbis(4-pyridy)silanes

  摘要：

  Investigations into pure bidentate ligand vs mixed bidentate ligands on self-assembly of AgPF6 with the respective L-1, L-2, L-3, L-1/L-2, L-1/L-3, and L-2/L-3 (L-1 = diethylbis(4-pyridyl)silane; L-2 = ethylmethylbis(4-pyridyl)silane; L-3 = cyclotetramethylenebis(4-pyridyl)silane) were carried out. The self-assembly reactions of AgPF6 with the respective ligand system produce desirable homoleptic or heteroleptic silver(I) coordination polymers. [Ag(L-1)(2)](PF6) gives rise to a tubular loop chain whereas the other five products lead to a twofold interpenetration diamonoid structure. [Ag(L-1)(2)](PF6) shows a strong blue luminescence at 453 nm (lambda(ex) = 270 nm), which is useful to recognize alcohols. All products were characterized by thermal analyses, and in particular, calcination of [Ag(L-3)(2)](PF6)center dot CH3OH at 600 degrees C finally produces silver(0) micro-crystalline morphology.

  triflate with L in alcohol solvent produces characteristic triple-meso helices [Ag3(L)3(ROH)](CF3SO3)3 (L = diethylbis(4-pyridyl)silane; R = Me, Et, n-Pr, and n-Bu) with six units in each turn. Their unit cell volumes are sensitive to the size of the coordinated alcohol molecules. An unusual “alcohol molecules at triple-meso helices” system is a characteristic reversible alcohol container and discriminator
