Design Principles of Self-assembled Superstructures of Polyhedral Metal-organic Framework Microparticles
Periodic superstructures often exhibit excellent optical properties and are of significant importance in the fields of photonics,catalysis,and sensing.Here,an acoustic levitation and a droplet method were employed to explore the assembly strategies of multidimensionally ordered metal organic framework(MOF)microparticle superstructures.The relationships between assembly parameters and the dimensions and the order of the superstructures were established.The results revealed that the acoustic levitation method demonstrated strong tolerance towards concentration and particle monodispersity,making it suitable for the self-assembly of three-dimensional superstructures.On the other hand,the droplet method had higher requirements on the concentration of suspensions and particle monodispersity,enabling the fabrication of large-area two-dimensional MOF microparticle monolayers.This study offers a novel approach for the assembly of multidimensional superstructures utilizing anisotropic microparticles.
