Cocrystal engineering is a strategy for assembling organic molecules via the non-covalent interaction force, avoiding harsh experimental conditions (i.e., high temperature and high pressure). By selecting the appropriate components, the donor-acceptor (D-A) molecules can be assembled like the jigsaw puzzle. Under the intermolecular interaction, such as π–π interactions, hydrogen bonds, and halogen bonds, cocrystal can not only display the intrinsic properties of its components but also show some novel properties, which can realize the “1+1>2” effect. So cocrystal strategy has the advantage in designing multifunctional materials.
