Engineering homologous molecular organization in 2D and 3D. Cocrystallization of aminoazines and alkanecarboxylic acids

Abstract

Amino-substituted azines such as aminotriazines have simple planar structures with an affinity for adsorption on graphite. In addition, aminoazines associate predictably with carboxylic acids according to a reliable hydrogen-bonded motif. Together, these properties help predispose aminoazines and alkanecarboxylic acids to cocrystallize and to coadsorb on graphite to give related 3D and 2D structures built from essentially planar tapes. These results illustrate how molecular materials that reliably adopt similar ordered structures in both adlayers and bulk samples can be devised by choosing components that combine an affinity for surfaces with a tendency to form sheets held together by strong coplanar intermolecular interactions.
