Dioxadiazuliporphyrin is a nonaromatic porphyrinoid, readily and reversibly oxidizable to its cation radical and to the aromatic carbaporphyrinoid dication, which can be viewed as a 21,23-dicarba-22,24-dioxaporphyrin with two fused tropylium rings. Further insight into the geometric and magnetic manifestations of aromaticity and antiaromaticity in the case of the redox couple 8, 82+ is obtained using
报道了二恶二氮杂卟啉原7的合成及其氧化形式:二恶二氮杂卟啉8和指示剂8 2+。这些化合物的特征在于使用UV-vis溶液,1 H和13 C NMR光谱仪在溶液中以及通过单晶X射线衍射分析处于固态。Dioxadiazuliporphyrin是一种非芳香族卟啉,可容易且可逆地氧化成其阳离子基团和芳香族碳卟啉类指示剂,可以将其视为具有两个稠合对苯甲基环的21,23-dicarba-22,24-dioxaporphyrin。在氧化还原对8的情况下,进一步了解芳香性和抗芳香性的几何和磁性表现,使用密度泛函计算和独立于核的化学位移获得8 2+。
