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‐twisted‐annuleno)doubly‐twisted‐annulene variants. All these decaphyrins display distinct Hückel aromaticity owing to the global 46π‐electronic networks but the contributions of the local half circuits were almost negligible due to the perpendicular orientation of the bridges.
