Sterically crowded and twisted thienylene-phenylenes were prepared and in cooperation with the University of Kiel characterized with various methods. Evidence of through-space delocalization of π-electrons in a catenated topology was found. The results are described in our recent publication in Eur. J. Org. Chem. (2020, 285-294) with the title „Twisted Thienylene-Phenylene Structures: Through-Space Orbital Coupling in Toroidal and Catenated Topologies“.
