Oriented self-assembly of metal–organic frameworks driven by photoinitiated monomer polymerization

Abstract

The self-assembly of metal–organic frameworks (MOFs) is crucial for the functional design of materials, including energy storage materials, catalysts, selective separation materials and optical crystals.

Metal‐Organic Framework‐Based Colloidal Particle Synthesis, Assembly, and Application

“…Along a similar evaporation-induced interfacial procedure, a monolayered or multilayered CMOF membrane with higher mechanical stability can be achieved. Fan et al [112] reported an approach to drive directional self-assembly of CMOF particles at the water-liquid interface by photoinitiated monomer polymerization. A mixed solution containing CMOF particles (MIL-96 or UiO-66) and photo-responsive monomer was dropped onto the water surface and illuminated using UV light to initiate monomer polymerization.…”

Facet-controlled assembly for organizing metal-organic framework particles into extended structures

“…Compared with other MOF processing approaches including MMM, monolithic growth, and hot-pressing, the assembled MOF material can inherit the anisotropic and facet-selective structural properties associated with crystal lattices, including well-aligned metal sites and oriented open channels, leading to enhanced efficiency and selectivity of mass transportation and other physical properties ( Figure 1 ). 22 , 23 , 24 , 25 As an example, the Cu-MOF films with aligned (001) orientation exhibited significantly enhanced electric and photocurrent properties in comparison to the Cu-MOF films with (100) orientation. 26 Moreover, the assembly of MOF particles in a well-controlled orientation was reported to enhance the mass transfer efficiency and gas permeability of the membrane.…”
