摘要: 光度分析的主要方向是研制对金属离子具有高灵敏度与高选择性的有机光度显色剂。通常作法是对给定分析功能团的母体,根据经验引入不同位置与类型的取代基,或通过寻找新的分析功能团,以期得到分析性能上的改善。

Abstract: Fluorone photometric reagent series have been studied with a computer program of PPPmethod for the electronic structures, and photometric properties of the organic reagents determined by experiments were compared with the calculated results and a good agreement was found. Some rules were presented by analyzing the calculated results. The conclusion indicated that substituent effects on the photometric properties of reagents and their metal complexes are not obvious.

Key words: Organic photometric reagents, Fluorone reagent series, PPP method
