用光度法测定四苯基卟啉及其衍生物的表观质子化常数

Determination of Over-All Protonati on Constants for Tetraphenylporphyrin and Its Derivatives by Spectrometry

本文用光度法测得九种不同卟啉化合物的质子化常数,并用HMO和MNDO方法计算了有关分子和分子单元,理论分析解释了实验结果。

Absorption spectra in the visible and ultraviolet regions for tetraphenylporphyrin and its derivatives are determined. Their over-all protonation constants were obtained. The molecules and molecular units for some tetraphenylporphyrins were calculated by HMO and MNDO methods. The basicities of taese compounds were explained.
