摘要

Two metal-organic frameworks (MOFs) with 3D structures, {[CO24(BDPO)(12)(H2O)(12)]center dot 18DMF center dot 40H(2)O}(n) (1) and {[NH2(CH3)(2)](4) [Zn-3(HBDPO)(2)(SO4)(2)]}(n) (2), were successfully synthesized based on Co-II and Zn-II inorganic nodes with the same bridging organic ligand (H4BDPO). Compound 1 possesses a relatively high BET surface area (similar to 1014 m(2)g(-1)) with multiple pore systems and basic catalytic centers to be applied as an efficient heterogeneous catalyst. The resultant 2 exhibits a 3D structure based on Zn(COO)(4) and Zn-2(SO4)(2)(COO)(2) as inorganic secondary building units. Thanks to its luminescence property, 2 is able to be considered as a platform for a recyclable biresponsive luminescence sensor for explosives and antibiotics via luminescence quenching effect. The high selectivity of 2,4,6-trinitrophenol can be estimated by the K-sv value of similar to 1.2 X 10(4)M(-1). Significantly, 2 can efficiently detect nitrofurantoin and nitrofurazone, and the corresponding K-sv values are 4.5 X 10(4) and 4.9 X 10(4) M-1, respectively.
