“…In an effort to improve the activation procedure and achieve a higher surface area, we carried out a solvent exchange by soaking a sample of the as-synthesized Ni 3 (BTC) 2 in anhydrous methanol for 24 hrs. This approach of exchanging DMF and other high boiling solvents with more 75 volatile ones has proven effective at facilitating evacuation and exposing UMCs in other MOFs. 61 After this treatment, powder X-ray diffraction confirmed retention of sample crystallinity, and FT-IR spectroscopy showed the disappearance of the DMF ν(C=O) stretching band at 1670 cm -1 ( Figure S2).…”

“…Ovendried sample tubes equipped with TranSeals™ (Micrometrics) were evacuated and tared. Samples (100-200 mg) were transferred to the sample tube, which was then capped by a 75 TranSeal™. Samples were heated to the appropriate temperatures and held at those temperatures until the outgas rate was less than 2 mTorr/minute.…”

The synthesis, activation, and heats of CO 2 adsorption for the known members of the M 3 (BTC) 2 (HKUST-1) isostructural series (M = Cr, Fe, Ni, Zn, Ni, Cu, Mo) were investigated to gain insight into the impact of CO 2 -metal interactions for CO 2 storage/separation applications. With the use of modified syntheses and activation procedures, improved BET surface areas were obtained for M = Ni, Mo, and Ru. 10The zero coverage isosteric heats of CO 2 adsorption were measured for the Cu, Cr, Ni, Mo, and Ru analogs and gave values consistent with those reported for MOFs containing coordinatively unsaturated metal sites, but lower than for amine functionalized materials. Notably, the Ni and Ru congeners exhibited the highest CO 2 affinities in the studied series. These behaviors were attributed to the presence of residual guest molecules in the case of Ni 3 (BTC) 2

“…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 amino group in the ligand backbone forms an N3-H3BÁ Á ÁO3 intramolecular hydrogen bond (see Table 2). Amino-functionalized porous coordination frameworks have recently attracted much attention because of an enhanced capacity for CO 2 adsorption (Couck et al, 2009;Vaidhyanathan et al, 2009).…”
