摘要: 基于分子结构与性质的相关性, 对已知能在液相产生直接化学发光的典型化合物进行了结构分析, 提取出与液相直接化学发光特性相关的分子拓扑指数, 以向量夹角余弦系数为判别指标构建了判别方程. 并用所建立的化学发光判别函数对101种生物活性化合物的化学发光特性进行了理论预测, 正确率为95.05%.

关键词: 液相直接化学发光, 分子拓扑指数, 夹角余弦系数, 分子结构与性质相关性

Abstract: Based on the quantitative structure-property relationship studies, molecular topology indices were used to describe the structure of some classical active compounds, which could react with common oxidants in a liquid phase to produce chemiluminescence emission, and some inactive compounds. The discriminant function was suggested with cosine coefficient as a descriptor. Finally, the discriminant function was applied to predicting the direct chemiluminescence behavior of 101 compounds with a success of 95.05%. The present work would give new idea to quickly develop suitable direct chemiluminescent analytical method in rather simple way.

Key words: Direct chemiluminescence in liquid phase, Molecular topology indice, Cosine coefficient, Quantitative structure-property relationship
