Protonation of meso‐aryl [28]hexaphyrins(1.1.1.1.1.1) triggered conformational changes. Whereas protonation with trifluoroacetic acid led to the formation of monoprotonated Möbius aromatic species, protonation with methanesulfonic acid led to the formation of diprotonated triangular antiaromatic species. A peripherally hexaphenylated [28]hexaphyrin was rationally designed and prepared to undergo diprotonation
介孔芳基[28]六卟啉(1.1.1.1.1.1)的质子化触发构象变化。三氟乙酸的质子化导致单质子化的莫比乌斯芳香族物质的形成,而甲磺酸的质子化导致双质子化的三角抗芳族物质的形成。合理设计外围六苯基化的[28]六氢卟啉,并准备对其进行双质子化处理,以有利地提供三角形的抗芳族物质。
