摘要
A hydrostable and bromine-functionalized MOF with a sxd topology constructed from tetranuclear clusters, {[Mn 2 (Bript) 2 (4,4'-bpy) .5 (DMF)]·(H 2 O)} n ( 1 ) (H 2 Bript = 4-Bromoisophthalic acid, 4,4'-bpy = 4,4'-bipyridine, DMF = dimethylformamide) was synthesized and structurally characterized. TGA and PXRD results show high thermal and water stability for the framework. 1 displays a 3D framework with the channel of 4.6 × 4.6 Å 2 along the c axis. The framework exhibits a reversible and highly selective luminescent sensing function with respect to Hg 2+ cation. Magnetic measurements reveal that the presence of weak antiferromagnetic couplings between the four Mn(II) ions in 1 .
