“…For ller contents higher than 5 wt%, the T g of the MMMs showed a downward trend due to the agglomeration of hZIF-L akes in the membrane matrix. 42 These results agree with the SEM observations of the MMMs (Fig. 9).…”

“…Given the similar structures of COF-TAPB-BTCA and UiO-66-NH 2 @COF-TAPB-BTCA beads (i.e., aC OF shell with internal hollowing), we attributed the higher surface area in the latter to the formation of pores of quasi-microscale (also known as supermicropores) in the interfaces between the MOF and COF crystals. [16] Formation of these pores was also reflected by the pore-size distribution (PSD;S upporting Information, Figure S13). TheP SD of UiO-66-NH 2 @COF-TAPB-BTCA showed the characteristic pore populations of both UiO-66-NH 2 (pore size,c a.…”

Herein, we describe an ew class of porous composites comprising metal-organic framework (MOF) crystals confined in single spherical matrices made of packed covalentorganic framework (COF) nanocrystals.T hese MOF@COF composites are synthesized through at wo-step method of spray-drying and subsequent amorphous (imine-based polymer)-to-crystalline (imine-based COF) transformation. This transformation around the MOF crystals generates micro-and mesopores at the MOF/COF interface that provide far superior porosity compared to that of the constituent MOF and COF components added together.W er eport that water sorption in these new pores occurs within the same pressure window as in the COF pores.O ur new MOF@COF composites,w ith their additional pores at the MOF/COF interface,s hould have implications for the development of new composites.

“…Zhao et al. designed MOF‐COF hybrids as fillers in MMM by coating size‐selective UiO‐66‐NH 2 cores with COF layers to increase the polymer‐filler compatibility (Figure e) . The organic nature of COF layers supported high affinity to the polysulfone matrix and avoided the formation of nonselective interfacial voids and agglomeration of UiO‐66‐NH 2 .…”

Traditional films cannotf ully adapt to industrial applicationsa nd to intensified processes. Advanced mixedmatrix membranes comprising metal-organic frameworks (MOF) embedded in ap olymer matrix have been developed with the goal of breaking the trade-offe ffect of traditional polymer membranes and achieving separation performance beyond Robeson's upper limit. The key challenges in the fabrication of MOF-based mixed-matrix membranes are an enhancementi nc ompatibility between the inorganic filler and the polymer matrix, elimination of the irregular mor-phologyand non-selectiveinterfacial defects, and further improvement in the gas-separation performance. This review summarizes the recent advances in protocols and strategies in terms of designing interfacial interactions to enhancet he MOF/polymer interface compatibility. This review aims at providing some meaningful insights into preparing MOFbased mixed-matrix membranes targeting ideal interfacial morphology and leading to excellent gas-separation performance.
