A novel three-dimensional lanthanide organic framework {[En(BTB)(phen)]center dot 4.5DMF center dot 2H(2)O}(n) (1) has been synthesized. Structural characterization suggests that framework 1 possesses one-dimensional channels with potential pore volume, and the large channels: in the framework Can capture-CO2. Interestingly, investigations on the,cycloaddition reaction of CO2 and epoxides reveal that compound 1 can be considered as an efficient catalyst for CO2 fixation with epoxides under 1 atm pressure. Importantly, 1 can be reused-at least five times-without any obvious loss in catalytic activity. Furthermore, the luminescent explorations of 1 reveal that 1 can at as a recyclable sensor of Al3+, and the corresponding detection limit can reach 5 x 5 10(-8) M (1.35 ppb), which is obviously lower than the United States Environmental Protection Agency's recommended level of Al3+ in drinking water (200 ppb).,These, results show that 1 has a level of sensitivity-higher than that of other reported MOF-based sensors of Al3+.
