本文从带有多电子共轭基团的酯多烯链物、苯多烯链物、联苯链物等各种系列同系物的电子光谱,研究多电子共轭基团的结构效应。用同系线性规律的专一性,同系直线间的相似三角形以及由诱导效应指数和共轭效应指数计算出的代基当量s值等方法,对18种不同的共轭体系,二百多种化合物进行了计算,确定了多电子共轭基团的效应;讨论了影响氧属基团的结构因素. In this paper, the structural effects of multi-electron conjugated groups are studied from the electronic spectra of various series of homologues of polyene chains with multiple electron conjugated groups, benzene polyene chains and biphenyl chains. With the specificity of linear regularity of homology, the similarity triangle between homologous lines and the equivalent s value calculated by inductive effect index and conjugate effect index, 18 different conjugated systems, over 200 compounds The calculations were carried out to determine the effect of multiple electron conjugated groups; the structural factors that affect the oxygen group were discussed.
