五种银配位聚合物，分别为：{[Ag(3，3‘-DAPS)2]·BF4}n(1)，{[Ag(3，3’-DAPS)2]·NO3}n(2)，[Ag(3，3‘-DAPS)(CF3SO3)]n(3)，{[Ag(4，4’-DAPS)]·CF3SO3}n(4)，{[Ag(4，4‘-DAPS)]·ClO4}n(5)(3，3’-DAPS=二(3‘-氨基二苯基)磺酸，合成了4，4‘-DAPS=二(4’-氨基二苯基)砜，并用元素分析、红外光谱、粉末X-射线衍射和单晶X-射线衍射法对其结构进行了表征。络合物1显示一维梯形链，具有四个连接的银离子和桥联的3，3‘-DAP。Complex2展示了用触手修改的其他一维梯子链。络合物3为二维层状结构，同时含有Ag离子，3，3‘-DAP为3-连接节点。络合物4是另一个一维梯形链，具有三个连接的银离子和4，4‘-DAP。Complex5显示了一个以Ag离子和4，4‘-DAP为4-连接节点的44-二维SQLnet。此外，还研究了它们的固态发光和热稳定性。
Five silver coordination polymers, namely, {[Ag(3,3′-daps)2]·BF4}n(1), {[Ag(3,3′-daps)2]·NO3}n(2), [Ag(3,3′-daps)(CF3SO3)]n(3), {[Ag(4,4′-daps)]·CF3SO3}n(4), and {[Ag(4,4′-daps)]·ClO4}n(5) (3,3′-daps=di(3′-aminodiphenyl)sulfone, and 4,4′-daps=di(4′-aminodiphenyl)sulfone) have been synthesized and structural characterized by elemental analyses, IR spectra, powder X-ray diffraction (PXRD) and single-crystal X-ray diffraction analyses. Complex1displays a 1D ladder-like chain with four-connected Ag ions and bridged 3,3′-daps. Complex2shows other 1D ladder chain modified by tentacles. Complex3is a 2D layer structure with both Ag ions and 3,3′-daps are 3-connected nodes. Complex4is another 1D ladder chain with three-connected Ag ions and 4,4′-daps. Complex5shows a 2D 44-sqlnet with Ag ions and 4,4′-daps as 4-connected nodes. Moreover, their solid state luminescence and thermal stabilities also have been investigated.
