architectures that possess both 1D π‐stacked columns and inclusionchannels were constructed by symmetry‐decreasing crystallization of dehydrobenzo[12]annulene (DBA) derivatives with naphthyl arms and C3symmetry (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.
