Résumé
Two shape-persistent star mesogens with oligo(phenylene ethenylene) arms and a phthalocyanine core-one providing free space (2) and one sterically encumbered by four fullerenes attached through spacers (3)-have been successfully synthesized. In contrast to the smaller discotic derivative 1, mesogen 2 forms a columnar liquid crystal (LC), which can only be partially aligned without π-stacking, while 3 is not an LC. Exceptionally, the 1:1 mixture of 2 and 3 forms an alignable columnar LC with strong π-stacking and quadruply helically organized fullerenes by an unprecedented click process that is similar to a ball detent mechanism.
