Abstract: Used ultraviolet spectrum titration method to study the three Coumarin derivatives and anionic special recognition behavior, compared the receptors of anion molecular structure, and the influence of anion concentrations on the coordination compounds absorption spectrum. We used the UV-Vis method to study the recognition of the receptors to the different kinds of anion(such as F-、Cl-、Br-、Ac-、H2PO4-、HSO4- ), some of receptors can bind well with anion through hydrogen bond because of the good orientation and the selectivity of the hydrogen bond, so it has good selectivity and recognition to the some anion(such as F-、Ac-、H2PO4-), and with almost no effect on the other anions.

Key words: coumarin, anion recognition, UV-Vis method
