Lower oxidation potentials than for the monomeric starting materials are displayed by the diporphyrins obtained by one-electron oxidation with tris(4-bromophenyl)ammonium hexachloroantimonate [see, for example, Eq. (1)]. This and the strong red shift observed for the Soret bands of the product are indicative of extensively delocalized pi-electron systems in the fused diporphyrin. Ar=3,5-di-tert-butylphenyl.
通过用三（4-溴苯基）铵六氯锑酸盐进行单电子氧化得到的双卟啉显示出比单体起始原料更低的氧化电位[例如，见式（1）]。产物的Soret带观察到的这种情况以及强烈的红移表明稠合双卟啉中存在广泛离域的π电子体系。Ar = 3,5-二叔丁基苯基。
