Abstract

original image

A 1D, π-stacked, columnar assembly composed of discotic π-conjugated molecules is one of the key architectures for organic semiconductor materials. In their Communication on page 14348 ff., I. Hisaki, M. Miyata et al. demonstrate that a supramolecular architecture with both 1D π-stacked columns and inclusion channels can be constructed through symmetry-decreasing crystallization by using a dehydrobenzo[12]annulene derivative with C3 symmetry. The structure experiences spontaneous guest desorption under ambient conditions; this results in shrinkage of the crystallographic cell.
