Abstract

original image

Supramolecular architectures that possess both 1D π-stacked columns and inclusion channels were constructed by symmetry-decreasing crystallization of dehydrobenzo[12]annulene (DBA) derivatives with naphthyl arms and C3 symmetry (see figure). The crystallization can be interpreted as i) formation of a two-fold column, ii) layer formation, and iii) lamination of the layer accompanied by guest inclusion.
