摘要

A novel uninodal 5-connected metal-organic framework (MOF), [Cd_2L_2(4,4′-bipy)_(3/2)(H_2O)_2]_n (H_2L=m-thioacetatebenzoic acid and 4,4′-bipy=4,4′-bipyridine), was prepared under hydrothermal condition. It features an unusual brick-wall shape layer by 4,4′-bipy, which consists of right- and left-handed helical chains arrayed alternatively and finally expands by L~(2-) to a rare 5-connected nov (4~4.6~6) topology network. Photoluminescence study reveals that it displays intense structure-related fluorescent emission bands (λ_(ex)=355 nm) at 450 nm in the solid state at room temperature.
