In agreement with theory, the title compounds 1 and 2, which were prepared by CpCo-catalyzed cycloisomerizations of appropriate oligoalkynylbenzenes, display physical properties that are in contrast with those of the corresponding linear isomers, but that are very similar to those of the angular topomers.
