Local and global dynamics in organic soft porous crystals

Summary

Organic soft porous crystals (OSPCs) have garnered significant attention for their potential applications in guest capture, gas storage, separation, and modulated optoelectronics. The diffusion processes within OSPCs are believed to be influenced by factors such as electronic affinity, guest size, shape, and importantly, the dynamic behavior of their backbones. This review highlights representative examples of these porous crystals that have been reported in recent years, focusing on materials with motion in their molecular components. Additionally, it describes instances where the segmental dynamics are also associated with changes in the crystal lattice, establishing a potential three-way connection between internal and global motion and other observables. By delving into the dynamic features of these materials, this review aims to provoke detailed analyses and discussion and to encourage more studies of this topic, which would contribute to a better comprehension of the intriguing properties of porous organic crystals.
