通过用六氯锑酸三（4-溴苯基）铵单电子氧化获得的二卟啉显示出比单体起始材料更低的氧化电位[参见例如Eq.①]。这一点和对产物的Soret带观察到的强红移表明稠合双卟啉中广泛的离域π-电子系统。Ar= 3，5-二叔丁基苯基。
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 π-electron systems in the fused diporphyrin. Ar=3,5-di-tert-butylphenyl.
