摘　　要：本文以4,4'-联苯二甲酸-2,2'-二磺酸(H4L)、1,3,5-三(对-咪唑基苯基)苯(TIPB)及钴盐为原料合成金属有机框架{[Co (TIPB)(L)_(0.5)]·5CH_(3)OH·2H_(2)O}_(n)晶体结构分析表明该化合物为磺基芳香酸L^(4-)配体支撑CoII-TIPB二维层形成的三维微孔框架。该结构中具有41.5%的孔隙率且孔道中充满磺酸基基团。质子传导测试表明化合物在80℃下的质导σ分别为1.34×10^(-4)S/cm,质子传导活化能为0.58 eV,说明该化合物是一种良好的质子传导材料。The metal-organic framework{[Co (TIPB)(L)_(0.5)]·5CH_(3)OH·2H_(2)O}_(n) was synthesized by 4,4'-biphenyl-2,2'-disulfonic acid(H4L),1,3,5-tris(4-imidazolylphenyl)benzene(TIPB)and cobalt salts.Structural analysis of the crystal structure reveals that the compound is a three-dimensional porous framework with CoII-TIPB two-dimensional layers supported by the sulfonyl aromatic acid L4-ligands.The structure exhibits a structural porosity of 41.5%with the pores filled with sulfonyl groups.Proton conductivity measurement indicates proton conductivityσof compound at 80℃is 1.34×10^(-4) S·cm^(-1),and the proton conductivity activation energy is 0.58 eV,suggesting its potential applications as proton conducting material.
