“…Chiral ligands can be used for the generation of homochiral porous MOFs, or chirality can be induced from the arrangement of achiral ligands within the structure. [54][55][56][57] Among the chiral ligands available, [58][59][60][61][62][63][64] bio-ligands, such as natural occurring peptides, are structurally rich and versatile with numerous metal binding sites. However, robust and highly porous MOFs based on these ligands are scarce in the literature.…”

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.

“…Recently, the relative isostatic stability of a series of ZIFs type compounds based on zinc, lithium, or boron has been analyzed. [34] If a relationship between the density of the porous solid and its Young modulus exists, the importance of the flexibility and stiffness of the inorganic SBU has been highlighted.…”

Crystalline porous materials with diverse chemical compositions (e.g., inorganic porous materials, inorganic-organic hybrid frameworks, and covalent organic frameworks) and framework topologies have been intensively studied in the past 60 years.[1] They have wide applications in fields such as heterogeneous catalysis, gas storage, and separation.[2] Moreover, some currently emerging areas related to health, energy use, and environmental conservation and remediation are still looking for the development of new porous materials. [3][4][5] Zeolites are among the most well known porous materials because of their typical 4-connected open frameworks with TO 4 (T = Si 4+ , Al 3+ , or P 5+ etc.) building blocks and outstanding catalytic or gas separation properties. [6,7] Recently, the search for new zeolite-like structures was extended to metal-organic frameworks (MOFs), and these explorations in part produced a variety of zeolitic imidazolate frameworks (ZIFs) ). [8][9][10][11] The rich chemistry associated with the organic imidazolate building blocks in ZIFs leads to some exceptional properties, such as large surface area and high gas uptake capacities.[12] A question that emerges is: "Are there material with properties intermediate of those of zeolites and ZIFs?". It is true that there is a hybrid state that remains unknown to date.In this work, we were seeking to integrate compositional and structural features of zeolites and ZIFs by combining TO 4 tetrahedra with zinc-imidazolate units. Such a combination is trusted to bear both merits of zeolites and ZIFs, for example, possession of catalytic active TO 4 sits of zeolites and high porosity of ZIFs. Herein, we report this kind of hybrid zeolitic imidazolate framework [denoted HZIFs; general formula: M 4 (im) 6 TO 4 ] with catalytically active TO 4 (T = Mo 6+ or W 6+ ) building blocks and high thermal stability (up to 550 8C), which presents a new class of porous materials filling the gap between zeolites and ZIFs.The HZIFs reported herein are constructed from two kinds of tetrahedral building blocks and contain two kinds of connectivity, and combine structural features of both zeolites and ZIFs (Scheme 1). The TO 4 or WO 4 2À anions, and 2-methylimidazolate (2-mim) under solvothermal conditions. Both compounds were structurally characterized by single-crystal X-ray diffraction and found to be isostructural. They crystallize in the same cubic space group Im " 3 3m and have neutral three-dimensional frameworks Zn 4 (2-mim) 6 TO 4 ·x(solvent) (HZIF-1Mo: T = Mo; HZIF-1W: T = W) containing structurally disordered solvent molecules. In each structure, the tetrahedral TO 4 unit bonds to four Zn centers and the tetrahedral geometry of each Zn center is completed by three 2-mim ligands (Scheme 1 c). The whole framework topology is identified as the 4-connected net with symbol sdt, [13] which is still unknown in both zeolites and ZIFs. A prominent structural feature of this sdt-type framework is to interconnect the truncated octahedral cages of 36 ] by the inorganic Mo...
