摘要: 计算了20种不对称变色酸双偶氮膦酸型显色剂的Am拓扑指数和分子联接性指数,并将其与镱显色反应灵敏度进行相关性研究,讨论了显色剂结构对拓扑指数及灵敏度的影响。

关键词: 拓扑指数, 显色剂, 构效关系

Abstract: In this paper Amtopological indices and molecular connectivity inidces have been applied to multivariate analysis in structure-property studies.The topological indices of twenty asymmetrical phosphone bisazo derivatives of chromotropic acid have been calculated.The structure-property relationships between color reagents and molar absorptivity of color reactions with ytterbium have been studied by Amindices and molecular connectivity indices.Good results have been obtained.

Key words: Topological indices, Color reagents, Structure-property relationship
