【発明の名称】オキサ酸のアニオンと選択的に相互作用するケト化合物、オキサ酸のアニオンとのアダクト、該アダクトの調製方法
Document Type and Number:
Japanese Patent JP2619906
Kind Code:
B2
Abstract:
Ketonic compounds, in which at least one strongly electron- withdrawing substituent is bonded to the carbon atom in the neighbouring position to the ketonic group and/or in which a pi -electron system is conjugated to the carbon-oxygen double bond of the ketonic group, have the capability to interact selectively with the anions of oxygenated acids, adducts, chelates or complexes being formed.
If the ketonic group is part of a chromophore in the corresponding ketonic compounds, a shift of the absorption in the visible or ultraviolet light region occurs on the formation of the adduct with the anions of the oxygenated acids.
The corresponding ketonic compounds can be used to detect the anions of the oxygenated acids, for example as an ion-sensitive component of an ion-sensitive part or as colour indicators.
