The cocrystallization of two small, common organic molecules, namely DL-2-phenoxypropionic acid and DL-proline, resulted in the formation of a hydrogen-bonded organic framework with a large unit cell. The obtained solid displays a structure possessing unidimensional ultramicroporous channels, whose functionality was shown by dynamic water vapor sorption and reversible xenon sorption assessed by in situ X-ray powder diffraction.
