摘要：
A series of triple-stranded complexes, [1a(3)Ag] BF4, [1b(3)Ag]BF4, [2a(3)Ag(2)](BF4)(2), [2b(3)Ag(2)](BF4)(2), and [3(3)Ag(3)](BF4)(3), have been obtained through the self-assembly of Ag-I ions with p-phenylene ethynylpyridine ligands. X-ray crystallographic studies unambiguously demonstrated a Ag-I-directed monodentate triple-stranded helical structure in the solid state for 1b and 2b. A combination of NMR spectroscopy, HRMS (ESI), and isothermal titration microcalorimetry studies further confirmed that strands 1, 2, and 3 are also able to form triple-stranded helical structures in the presence of Ag-I ions in solution.
