设计并合成了5种呋喃并[3’,4’:5,6]吡啶并[2,3-c]吡唑受体分子,利用紫外-可见吸收光谱考察了其与F-,Cl-,Br-,AcO-,HSO-4,H2PO-4等阴离子的作用.结果表明该类受体分子与阴离子形成氢键配合物,导致呋喃并吡啶并吡唑受体的光谱发生变化.测定了配合物的结合比和稳定常数,发现受体化合物对F-,AcO-离子具有良好的选择性,对其它多种阴离子无影响.Job曲线表明受体分子与阴离子间形成1∶1型的配合物. Five kinds of furo [3 ’, 4’: 5,6] pyrido [2,3-c] pyrazole acceptor molecules were designed and synthesized. Their molecular structures were studied by UV-Vis absorption spectroscopy. BrO, AcO-, HSO-4, H2PO-4 and other anions.The results show that the hydrogen-bonding complexes of these acceptor molecules with anion lead to the change of the spectrum of the furopyridopyrazole acceptor, The binding ratio and the stability constant of the acceptor compound, and found that the acceptor compound has good selectivity for F- and AcO- ions and has no effect on other kinds of anions. The Job curve shows that a 1: 1 type complex is formed between the acceptor molecule and the anion .
