A 4,4′-biimidazole, two kinds of quaterimidazoles, and a sexiimidazole were designed and synthesized for the first time as novel building blocks for supramolecules. The one-dimensional zigzag ribbonlike hydrogen-bonded structure of 4,4′-biimidazole containing protonated 4,4′-biimidazole was confirmed by single crystal structure analysis.
