文摘Four porous interpenetrating metal–organic frameworks(MOFs),namely,[Cd_(2)(Tipb)_(2)(btc)Cl]·G_(x)(1),[Cd(Tipb)(tdc)]·G_(x)2,[Cd(Tipb)(fdc)]·G_(x)(3),and[Cd_(5)(Tipb)_(4)(btc)_(2)Cl_(2)(DMF)_(2)(H_(2)O)_(5)]·Cl_(2)·G_(x)(4)(G=vip molecules,Tipb=1,3,5-tris(p-imidazolylphenyl)benzene,btc=benzene-1,3,5-tricarboxylic acid,tdc=thiophene-_(2),5-dicarboxylic acid,fdc=furan-_(2),5-dicarboxylic acid,and DMF=N,N′-dimethylformamide)have been assembled fromπ-electron-rich ligands and cadmium salts.These four MOFs exhibit strong fluorescent emissions upon excitation at room temperature.
