Luminescent organic porous crystals from non-cyclic molecules and their applications

Organic porous crystals from small and non-cyclic organic molecules can be constructed by various weak intermolecular interactions. Owing to their precise stacking types, intermolecular interaction and pore microstructure, the relationship between properties and structure is definite and then they may be applied in gas separation and storage, proton conduction, biological applications, chiral separation and structure determination. Among them, photoluminescent porous crystals have attracted special attention. The luminescence properties of the crystals are not only related to the single molecular structure, but also to the intermolecular stacking. A slight external stimulus can be amplified within the crystal system. Therefore, we focus on the recent development and some applications of porous photoluminescent organic crystals.
