A Zn-based, pillared paddlewheel MOF containing free carboxylic acids via covalent post-synthesis elaboration

Abstract

A Zn-based, mixed-ligand (pillared paddlewheel), metal-organic framework (MOF) has been covalently and quantitatively decorated with free carboxylic acids to demonstrate the utility of covalent post-synthesis modification in the construction of otherwise inaccessible carboxy-functionalized MOFs.

Microporous metal-organic framework with potential for carbon dioxide capture at ambient conditions

“…The regeneration energy cost to utilize these porous materials for CO 2 capture by the implementation of temperature swing adsorption, pressure swing adsorption (PSA) and vacuum swing adsorption is significantly lower than the abovementioned alkanolamine technology. More importantly, the rapid development over the past decade in this research field to target some porous MOFs for their extremely high uptake of CO 2 at high pressure 11,12 and to immobilize functional sites, such as open metal sites [13][14][15][16][17][18][19][20][21][22][23] , -NH 2 and -OH organic sites into the pore surfaces to enhance their interactions and thus enforce their efficient CO 2 separation selectivity have principally ensured the feasibility of porous MOFs for CO 2 capture [24][25][26][27][28][29][30][31][32][33][34][35][36][37][38] .…”

Amine-functionalized MIL-53(Al) with embedded ruthenium nanoparticles as a highly efficient catalyst for the hydrolytic dehydrogenation of ammonia borane

“…11 To date, a series of functionalized MOFs that incorporate a variety of functional groups (e.g., -OH and -NH 2 ) has been successfully prepared. 12,13 Among them, amine groups have attracted the most attention from researchers due to their ability to function as interaction sites for supported metallic nanoclusters in heterogeneous catalysis.…”

A new carboxyl-copper-organic framework and its excellent selective absorbability for proteins

“…This can be explained by the tendency of such reactive groups to engage in framework building through coordination or hydrogen bonding. The appeal of MOF materials that have free carboxylic acids is clear: they can be further modified using a wide range of reactions to afford new MOFs with different capabilities [9]. For example, such a MOF could be functionalized with a variety of metals, generating a series of new MOF materials with metal carboxylates in their pores, where each one can be used for a particular catalytic reaction [8,10].…”
