Sterically crowded and twisted thienylene‐phenylenes were synthesized and characterized in comparison to corresponding polyphenylene nanostructures. Spectroscopic, diffraction, and theoretical studies gave evidence of through‐space delocalization of π‐electrons of peripheral (hetero)aromatic rings in toroidal and catenated topologies.
