摘　　要：The development of new materials for the design of sensitive and responsive sensors has become a crucial research direction.Here,two silver cluster-based polymers(Ag-CBPs),including one-dimensional[Ag_(22)(L1)_(8)(CF_(3)CO_(2))_(14)](CH_(3)OH)_(2))n chain and two-dimensional[Ag_(12)(L2)_(2)(CO_(2)CF_(3))_(14)(H_(2)O)_(4)(AgCO_(2)CF_(3))_(4)](HNEt_(3))_(2))_(n) film,are designed and used to simulate the human nose,an elegant sensor to smells,to distinguish organic solvents.We study the relationship between the atomic structures of Ag-CBPs determined by x-ray diffraction and the electrical properties in the presence of organic solvents(e.g.,methanol and ethanol).The ligands,cations,and the ligated solvent molecules not only play an important role in the self-assembly process of Ag-CBP materials but also determine their physiochemical properties such as the sensing functionality.
