An o-p-biphenyl moiety-incorporated 32π hexaphyrin(3.1.1.3.1.1) is successfully achieved. Replacing ortho with meta connectivity in the biphenyl unit of hexaphyrin leads to the formation of its structural isomer, octaphyrin(1.1.1.0.1.1.1.0). Spectral and structural analyses reveal the lack of planarity in hexaphyrin and the presence of an m-arene unit in octaphyrin, thus affording nonaromatic characteristics.

嵌入六邻卟啉(3.1.1.3.1.1)和八邻卟啉(1.1.1.0.1.1.1.0)的结构异构化的双联苯部分。

成功实现了一个带有op-联苯部分的32π六卟啉(3.1.1.3.1.1)。用六连接蛋白的联苯单元中的间连接性取代邻位导致其结构异构体八连接蛋白(1.1.1.0.1.1.1.0)的形成。光谱和结构分析表明,在六卟啉中缺乏平面性并且在八卟啉中存在间芳烃单元,因此提供了非芳香族特性。
