“…MOFs have emerged as promising materials for the selective capture and utilization of CO2.To date, research efforts have focused on generating open metal sites or incorporating ligands functionalized with Lewis basic groups; both strategies have shown to be promising for the selective capture of CO2 over other gasses such as N2 (flue gas) or CH4 (natural gas). [1,20,28,[175][176][177][178][179][180][181][182][183] Bio-ligands can be decorated with multiple groups which can be incorporated into bio-MOFs which can be promising candidates for the selective capture of CO2.…”

Metal organic frameworks (MOFs) are extended structures composed of a network of organic ligands and metal ions or clusters connected to each other via coordination bonds. The numerous choices of organic ligands and metal coordination geometries have led to the construction of porous MOFs with various compositions, network topologies, pore sizes and shapes and they possess high surface areas and low densities. The structures of MOFs can be tailor-tuned in such a way that any desired ligand or/and metal ion can be incorporated; this has given to researchers the advantage of designing MOFs for a targeted application. Within this review, we overview recent examples of a sub-class of MOFs namely biologically derived MOFs (bio-MOFs), made of multifunctional and commercially available biologically derived ligands (bio-ligands) such as: amino acids, peptides, nucleobases and saccharides and focus on their coordination chemistry with a variety of metals. Central to this review are four tables detailing the coordination modes of bio-ligands to metals, along with a visual representation of the bio-MOF that is subsequently formed. Through the detail analysis of these structures, we highlight the structural impact of these ligands on the structure, and their contribution to the MOFs properties and applications. Finally, we showcase the potential of bio-MOFs in several research areas such as CO2 capture, separation, catalysis, drug delivery and sensing.

“…The pores within porous MOFs, particularly those within isoreticular MOFs whose structures are pre-determined by the coordination geometries of the secondary building blocks, can be systematically modified by changing the organic bridging linkers and controlling the framework interpenetration [2][3][4][5] . Furthermore, the pore surfaces of porous MOFs can be functionalized by the immobilization of different recognition sites, such as open metal sites, Lewis basic/acidic sites and chiral pockets, to direct the recognition of small molecules [6][7][8][9][10][11][12][13][14] . Systematically tuning micropores can achieve size-specific encapsulation of small gas molecules, and immobilization of functional sites enables varying substrate interactions: microporous MOF materials have emerged as promising microporous media for the recognition and separation of small molecules [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32] .…”

Rationally tuned micropores within enantiopure metal-organic frameworks for highly selective separation of acetylene and ethylene

et al. 2011

separation of acetylene and ethylene is an important industrial process because both compounds are essential reagents for a range of chemical products and materials. Current separation approaches include the partial hydrogenation of acetylene into ethylene over a supported Pd catalyst, and the extraction of cracked olefins using an organic solvent; both routes are costly and energy consuming. Adsorption technologies may allow separation, but microporous materials exhibiting highly selective adsorption of C 2 H 2 /C 2 H 4 have not been realized to date. Here, we report the development of tunable microporous enantiopure mixed-

“…This is among the highest reported CO 2 uptakes for any MOPs at 298 K and slightly higher than the alcohol-functionalized phenolic resin network POF1B (2.14 mmol g −1 ) [36]. Amines are important functional groups that are usually used to enhance the isosteric heat, selectivity, and uptake capacity of CO 2 in the materials [37,38]. However, only few MOPs containing -NH 2 groups have been synthesized [39].…”

Microporous organic polymers (MOPs) are a unique class of porous materials consisting solely of the light elements (C, H, O, N, etc.). A series of vivid characteristics of MOPs, such as high-specific surface area, good physicochemical stability, diverse pore dimensions, topologies, and chemical functionalities, make them suitable adsorbents for CO 2 capture. In this chapter, MOPs are categorized into four classes according to the types of organic reactions and the chemical structures of the resulting materials: hypercrosslinked polymers (HCPs), covalent organic frameworks (COFs), polymers of intrinsic microporosity (PIMs), and conjugated microporous polymers (CMPs). For each type of the polymer network, the state-of-the-art development in the design, synthesis, characterization, and the CO 2 sorption performance is reviewed. Strategies for controlling CO 2 uptake capacity and adsorption enthalpy via manipulation of surface area, pore size, and functionality are discussed in detail. These studies would open up many new possibilities for the development of the novel solid sorbents targeting the CO 2 capture process. It is expected that this chapter will not only summarize the main research activities in this field, but also find possible links between basic studies and practical applications.
