| Abstract: | Solid‐state reactions have been rapidly gaining popularity in organic chemistry owing to their simplicity, efficiency, and selectivity compared to liquid‐phase reactions. Herein, we describe the formation of superstructures through the solid‐state reaction of an organic single‐crystal. The superstructure of 5,5′,5′′‐(1,3,5‐triazine‐2,4,6‐triyl)triisophthalonitrile (TIPN) can be formed by cyclotrimerization of 1,3,5‐tricyanobenzene (TCB) single crystals. The TIPN superstructure was confirmed by single crystal X‐ray diffraction and visualized by transmission electron microscopy. The superstructure has hexagonally packed 1‐dimensional (1D) channels along the crystal axis. Furthermore, the superstructure arises from interdigitated nitrile interactions in the crystal lattice, and thus has electron‐beam tolerance and very high thermal stability. |
