Abstract
(Chemical Equation Presented) We have demonstrated a triangular assembly driven by 12 charged hydrogen bonds and π-π interactions. This assembly is stable even in polar solvents because of its charged hydrogen-bond nature. Helical arrangement of the complex is confirmed by its crystal structure. A solution structure is assigned to the D3 isomer corresponding to the solid-state structure by temperature-dependent 1H NMR experiments.
