The Front Cover shows the molecular structure of a sterically crowded and twisted thienylene‐phenylene, leading to coupled p‐orbitals and potential through space delocalization of π‐electrons in a catenated topology, involving all ipso‐carbons of the peripheral thiophene rings. Such electronic effect was rationalized by advanced theoretical calculations and single crystal X‐ray structure analysis and, for the first time, identified for neutral molecules.
