Internally 3,3′‐biphenyl‐, 2,2′,5,5′‐bithiophene‐, and 2,5‐thieno[3,2‐b]thiophene‐bridged [46]decaphyrins were prepared. In addition to the global 46π‐conjugated circuits, the internal core‐modified [32]heptaphyrin‐ and [30]hexaphyrin moieties in 2,2′,5,5′‐bithiophene‐ and 2,5‐thieno[3,2‐b]thiophene‐bridged [46]decaphyrins also possess doubly twisted topologies (|Lk|=2) and are regarded as (doubly
内部-3,3'-联苯,2,2',5,5'- bithiophene-,和2,5-噻吩并[3,2- b ]噻吩桥连[46]制备decaphyrins。除了全局46π共轭电路外,内部核心修饰的2,32',5,5'-联噻吩和2,5-噻吩[3,2-]的[32]庚卟啉和[30]六卟啉部分b ]噻吩桥接的[46]十氢卟啉也具有双扭曲拓扑(| L k | = 2),被视为(双扭曲环)双扭曲环。由于全局的46π电子网络,所有这些十氢卟啉均表现出独特的Hückel芳香性,但由于桥的垂直方向,局部半回路的贡献几乎可以忽略不计。
