Three isostructural metal–organic frameworks denoted as Zn(L)(aip)·(H₂O) (1), Zn(L)(ip)·(DMF)(H₂O)_1.5 (2), and Zn(L)(HBTC)·(H₂O)₂ (3) with functional groups –NH₂, –H and –COOH, respectively, decorated on the 1D channels have been rationally designed with the purpose of exploring the influence of electron transfer from organic ligands in the 1D channels on the sensing of nitro explosives and antibiotics. These three compounds exhibit strong fluorescence in water, and they can be applied to detect the presence of explosives or antibiotics by means of fluorescence quenching in aqueous solution, whereas in terms of special explosives or antibiotics at the same concentration, 3 demonstrates a more superior quenching efficiency than 1 and 2. More importantly, it has been found that the difference in the sensing performances of these compounds is closely related to the interaction between the functional groups and guest molecules via electron and energy transfer from MOFs to explosives and antibiotics.

在硝基炸药和抗生素检测中探索锌-有机骨架的一维通道中官能团取代的工程设计†

三种同构的金属-有机骨架，分别表示为Zn（L）（aip）·（H ₂ O）（1），Zn（L）（ip）·（DMF）（H ₂ O）_1.5（2）和Zn（L ）（HBTC）·（H ₂ O）₂（3）带官能团–NH ₂一维通道上分别装饰的-H和-COOH经过合理设计，目的是探索一维通道中有机配体的电子转移对硝基炸药和抗生素的影响。这三种化合物在水中均显示强荧光，可以通过水溶液中的荧光猝灭法将其用于检测爆炸物或抗生素的存在，而就相同浓度的特殊爆炸物或抗生素而言，3表现出更好的猝灭作用效率比1和2。更重要的是，已经发现，在这些化合物的感测性能的差异密切相关的官能团和客体分子之间的相互作用通过从电子的MOF和能量转移到炸药和抗生素。
