Fig. 2: The crystal structure of AOTC cocrystal.

a Optical microscope images of the AOTC cocrystal taken under room light (left) and under 365 nm UV irradiation (right), and the crystal structure of AOTC. b The π···π interactions and C–H···N interactions in the crystal structure of AOTC. c IGMH analysis of the non-covalent interactions in AOTC. d Hirshfeld surfaces and decomposed fingerprint plots showing N···H interactions in AOTC, with the proportions of N···H interaction (PN···H) relative to total intermolecular interactions also indicated.
