摘要： Five diverse 1D supramolecular chains, {[4-pmntd]}(n)(1), {H-2[4-pmntd]center dot 2Br(-)}(n)(2), {H-2[4-pmntd]center dot 2NO(3)(-)}(n)(3), {H-2[4-pmntd]center dot 2ClO(4)(-)}(n)(4), {H-2[4-pmntd]center dot 2BF(4)(-)}(n)(5), (where 4-pmntd was N,N'-bis (4-pyridylmethyl)naphthalene diimide) were synthesized and characterized by X-ray single-crystal structure analysis, IR spectroscopy, elemental analyses, thermogravimetric analyses, fluorescence detection. The anions effect construction of their 1D chain structural diversity through different pi interactions. Compound 1 through the adjacent pyridine rings parallel pi center dot center dot center dot pi interactions formed 1D linear chain structure. Compound 2 through Br- anion center dot center dot center dot pi interactions and halogen bond interactions formed 1D zigzag chain structure. Compound 3 through lone pair center dot center dot center dot pi interactions of naphthalene diimide and the adjacent carboxyl group formed 1D stairway chain structure. Compound 4 through ClO4- anion center dot center dot center dot p interactions formed 1D ribbon chain structure. Compound 5 through parallel pi center dot center dot center dot pi interactions of the adjacent naphthalene diimide planes and pyridine rings formed 1D ladder chain structure. The five compounds' fluorescence properties and thermal stabilities were investigated. The compound 2 solution could fluorescence detection for iodide anion via fluorescence quenching.
