摘　　要：设计合成了一系列基于羟基和氨基的酰腙类受体分子.利用紫外-可见吸收光谱及1HNMR考察了其与F-,Cl-,Br-,I-,CH3COO-,H2PO4?,HSO4?,ClO?4等阴离子的作用.结果表明,该类受体分子在DMSO溶液中能较好地比色识别F-,CH3COO-,H2PO4?,其中受体2在含水介质中[V(DMSO)∶V(H2O)=7∶3]能选择性比色识别CH3COO-.1HNMR滴定实验研究了受体分子与阴离子之间的作用,结果表明受体分子与阴离子之间以氢键作用方式相结合.A series of colorimetric anions sensors bearing phenol OH and N H groups were syntnesized. The binding properties of the receptors with anions such as F-, CI-, Br , I , CH3CO0-, H2PO4, HSO4 and CIO4 in DMSO were examined by UV-Vis and 1H NMR spectra. The results showed that these sensors had a better selectivity for F-, CH3CO4- and H2PO-, but had no evident binding with CI-, Br-, I- , CIO4- and HSO4. Especially, the receptor 2 in F（DMSO） ： F（H20）= 7 ： 3 solutions indicated colorimetric single selectivity for CH3COO-.1H NMR titrations showed that there are hydrogen bonding interaction between the receptors and anions.
