Dissymmetrical substitution of norcorrole enables the preparation of various norcorrole derivatives as air- and moisture-stable species. Intramolecular charge transfer interactions between electron-donating substituents and the norcorrole core in these norcorroles significantly enhanced their low-energy absorption bands, which were forbidden in symmetrical Ni dimesitylnorcorrole.
降卟啉的不对称取代能够制备出各种作为空气和水分稳定物种的降卟啉衍生物。这些降卟啉中给电子取代基与降卟啉核心之间的分子内电荷转移相互作用显著增强了它们的低能量吸收带，而在对称的二甲基镍降卟啉中这些吸收带是禁阻的。
