摘　　要：Two silver（I）-sulfonate complexes,[Ag（NO3）（4,4＇-bipy）][Ag（HL）（4,4＇-bipy）]·2H2O（1） and[Ag（H2O）（4,4＇-bipy）][AgL（4,4＇-bipy）]·2H2O（2）,have been synthesized by in situ reaction（H2L = 2-formylbenzenesulfonic acid,4,4-bipy = 4,4-bipyridine）.1 displays two parallel 1D chains expending to a 3D supramolecule by n—n interactions and O-H…O hydrogen bonds,in which the[Ag（NO3）]or[Ag（HL）]units are joined by bridging 4,4＇-bipy molecules,respectively.The interactions between the complexes and DNA were studied by means of fluorescence spectra and surface-enhanced Raman scattering（SERS） spectra.The special configuration and intercalation effects between 1 and DNA are stronger than that between 2 and DNA.Two silver（I）-sulfonate complexes,[Ag（NO3）（4,4＇-bipy）][Ag（HL）（4,4＇-bipy）]·2H2O（1） and[Ag（H2O）（4,4＇-bipy）][AgL（4,4＇-bipy）]·2H2O（2）,have been synthesized by in situ reaction（H2L = 2-formylbenzenesulfonic acid,4,4-bipy = 4,4-bipyridine）.1 displays two parallel 1D chains expending to a 3D supramolecule by n—n interactions and O-H…O hydrogen bonds,in which the[Ag（NO3）]or[Ag（HL）]units are joined by bridging 4,4＇-bipy molecules,respectively.The interactions between the complexes and DNA were studied by means of fluorescence spectra and surface-enhanced Raman scattering（SERS） spectra.The special configuration and intercalation effects between 1 and DNA are stronger than that between 2 and DNA.
