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 carbazolesulfonyl hydrazide anion acceptor 1 with 1,8-naphthalimide signal units was designed and synthesized. Fluorescence and UV-vis spectroscopic titration experiments showed that 1 can selectively recognize compounds with important biological Receptor 1 and these anions form a 1: 1 complex and have a binding constant of greater than 103 L mol-1. Interestingly, in aqueous 10 % (V / V) of DMSO showed a specific recognition of F- 1. Magnetic resonance spectroscopy in DMSO-d6 showed that at lower concentrations of F-, receptor 1 interacted with its five intermolecular hydrogen bonds Produced an effective combination.
