Jc. Beeson et al., PI-COMPLEXATION IN THE SOLID-STATE INDUCED BY INTERMOLECULAR HYDROGEN-BONDING, Journal of the American Chemical Society, 116(11), 1994, pp. 4621-4622
Electron-deficient heterocycles, such as the hexaazatriphenylenes, avo
id pi-complexation in the solid state. We observe that interplane amid
e hydrogen bonding controls secondary structure and induces pi-complex
ation in the solid state of an organic hexaamide predisposed to avoid
it.
