“…Their ability to form inclusion complexes has been exploited in various areas of research (including MOFs) for drug carrier systems, the food industry, cosmetics and more. [149] The guest-host complex formation factors with organic molecules are Van der Waals, hydrophobic interactions, size effects and hydrogen bonding. [149] Saccharides, such as CD, are appealing bio-ligands for the construction of bio-MOFs as they can be prepared entirely from edible ingredients.…”

[149] Saccharides, such as CD, are appealing bio-ligands for the construction of bio-MOFs as they can be prepared entirely from edible ingredients. For example, the synthesis of γ-CD can be synthesized using a salt substitute (KCl) in bottled water and Everclear grain spirit.…”

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.

“…As was stated by Norkus [34], most of the thousands of papers published each year on cyclodextrins concern cyclodextrin inclusion complexes and only a few deal with cyclodextrin metal complex chemistry. Metal ion complexes with cyclodextrins can be considered as models of metallo-enzymes.…”

DFT studies of cation binding by β-cyclodextrin

Interactions of the b-cyclodextrin (b-CD) ligand with Na ? , Cu ? , Mg 2? , Zn 2? , and Al 3? cations were investigated using density functional theory modeling. The objective of this study was to give insight into the mechanism of cation complexation. Two groups of conformers were found. The first group preserved the initial orientation of glucopyranose residues inside the b-CD ligand. The mutual orientation of glucopyranose residues was strongly affected by the cation in the second group of conformers. The system interaction energy was decomposed into electrostatic (ES), Pauli and orbital contributions using the Ziegler-Rauk energy partitioning scheme. The total electrostatic energy, i.e., the sum of ES energy and polarization energy, is the dominating term in the interaction energy. In vacuum, the complexes formed with Al 3? were found to be more stable than with di-and monocations. The vacuum stability sequence was changed in aqueous solution.

“…Organic-inorganic hybrid strategy represents a very efficient methodology for the preparation of CD-silica hybrid CSPs and thus opens a new way to access new type of HPLC CSPs (such as macrocyclic compounds, protein or polysaccharides-based CSPs). These materials could have important applications in HPLC CSPs, large-scale preparation of chiral drugs and environmental protection (e.g., the remove of the heavy metal or organic pollutants in waste water) [42,43,51].…”
