【摘要】 合成了用于识别阴离子的主体分子——2,4-二羟基苯乙酮缩-2-萘甲酰腙(X),通过红外光谱、核磁共振谱和质谱表征其结构;研究了阴离子对X吸收光谱的影响。实验表明:在乙腈中,阴离子加入对X的吸收光谱影响大小为:F->H2PO4->AcO-,而Cl-、Br-、I-和HSO4-对X的吸收光谱几乎没影响。Job法实验得出X与F?的结合比为1:1。更多还原

【Abstract】 A kind of chemosensor for anions,1-(2,4-dihydroxyphenyl)ethanone-2-naphthoylhydrazone(X),was designed and synthesized.Receptor X was confirmed by IR,1HNMR and ESI-MS.X was investigated to recognize anions such as F-,AcO-and H2PO-4 via its absorption spectra.It was found that X showed highly selective response to F-in acetonitrile.The binding constants varied in general in the order of F->H2PO-4>AcO-whereas the other anions had little influence in the absorption spectra of X.Job’s test showed X coordinate with F-to form a complex with 1:1 binding model.更多还原
