摘要: 本文在分析四苯基卟啉及其衍生物结构基础上确定了标准反应焓  和超共振能ΔS-R  Phy-X,求出了它们的摩尔标准升华焓和气态摩尔标准生成焓,并结合HMO方法求出了这类化合物的张力焓、共振能及扭曲角。讨论了气态摩尔标准生成焓与取代基常数间的线性关系。

关键词: 张力效应, 共振效应, 扭曲角, 共振能

Abstract: Based upon the structural characteristics of tetraphenylporphyrin and its derivatives, we defined  Firstly, (这里有图片19920428-509-1.gif) and ΔS-R  Phy-X are determined, then the standard molar enthalpies of sublimation, the standard enthalpies of formation in gas phase are obtained.The enthalpies of strain, resonance energies and twisty angle of these compounds are also obtained by HMO method.The linear relationship between the gas phase standard enthalpies of formation and the substituent constants is discussed.

Key words: Strain effect, Resonance effect, Twisty angle, Resonance energy
