用电位法测定了40个邻菲咯啉取代物在25℃时的酸解离常数。数据外推，以求出水中不溶于水的衍生物的pffa值，表明在百分比、二恶烷和水-二恶烷溶液中的相对pica值之间存在线性关系。多个甲基取代基的Hammett取代基常数是相加的。
The acid dissociation constants of forty substitution derivatives of 1, 10-phenanthroline were determined potentiometrically at25. A linear relationship which permits extrapolation of data to find pffa values in water for derivatives insoluble in water was shown to be obtained between per cent, dioxane and relative piCa values in water-dioxane solutions. The Hammett substituent constants for methyl groups were shown to be additive for multiple methyl substituents.
