摘　　要：设计合成了一个新型的含1,8-萘酰亚胺信号单元的咔唑磺酰肼类阴离子受体1,荧光和UV-vis光谱滴定实验表明,1在DMSO中能选择性识别具有重要生物学意义的F-,Ac O-和2 4H PO-;受体1与这些阴离子形成1∶1的配合物,且它们的结合常数均大于103 L?mol-1.有趣的是,在含水10%(V/V)的DMSO中1对F-表现出了专一性识别.DMSO-d6中的核磁滴定表明,在F-浓度较低时,受体1通过五重分子间氢键作用与其产生了有效结合.A novel carbazole sulfonohydrazide receptor （1） bearing the 1,8-naphthalimide units was designed and synthe-sized, which selectively recognized biologically important F-, AcO- and H2PO4- in DMSO, as evidenced by fluorescence and UV-vis titration experiments. Receptor 1 formed 1∶1 complexes with these anions, affording the binding constants larger than 103 L？mol-1. Interestingly, receptor 1 displayed a specific recognition towards F？in DMSO containing 10%H2O （V/V）. The 1H NMR titration experiments in DMSO-d6 proved that five-fold intermolecular H-bonding interactions were responsible for effective complexation between 1 and F- （at a low concentration）.
