摘要: 对6种带羟基的分子内电荷转移化合物(其中化合物1,4,5,6含氰基基团)及与不同阴离子间的相互作用及其分子识别进行了研究.发现化合物2,3,5,6均对F-离子有优良的检测能力,并对H2PO4-有一定的响应能力,其中化合物2对AcO-离子也有一定的响应.对实验结果进行了初步讨论,并对提高敏感化合物的灵敏度和选择性提出了看法.

Abstract: The interaction and recognition between different anions and 6 kinds of intra molecular charge transfer compounds have been investigated in this paper. It is found that compounds 2, 3, 5 and 6 all possess an excellent ability to the detection of F-anion. They also show themselves to have nice response to the H2PO4-. And compound 6 has a selectivity for AcO- over H2PO4- anions. The experimental results have been discussed preliminary. And how to promote the sensitivity and the selectivity of these compounds are also discussed.

Key words: Anionic recognition and detection, Colorimetric method, Hydrogen bonding interaction
