What's it got in its pockets? Symmetry carry‐over crystallization of hexadehydrotribenzo[12]annulenederivatives was provided by specific complexation between the annulene and the chloroform molecule through mainly dispersion forces (see picture). In the complex, a hydrogen atom of the chloroform fits into the annulene's “pocket” surrounded by π electrons.
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.
