“…[133] One-dimensional Zn-adeninate chains were formed with adeninate connected to both building units in a 1:1 ratio. [133] In [121,134] The latter structure is shown to have reversible structural transformations upon removal and addition of H2O, giving a color change from pink to purple, respectively. [134] The indication of a color change implies a change in the coordination geometry of Co II from an octahedral to tetrahedral upon removal of coordinated H2O.…”

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.

“…Nowadays, biomolecules such as nucleobases, amino acids and peptides are preferred over synthetic ligands in the preparation of such compounds . These biomolecules are inexpensive, nontoxic and capable of forming hydrogen bonds, inducing chirality as well as providing multiple donor sites . Interestingly, nucleobases are of prime interests among biomolecules for the construction of CPs.…”

“…Among nucleobases, adenine is a more attractive building unit because of its rigid, planar and π‐conjugated structure . Moreover, it offers five potential donor sites including heterocyclic and imidazole nitrogen atoms (Scheme ) which can coordinate many metal ions or form hydrogen bonds and thus leading to new polymeric structures …”

A new Mn (II)‐containing coordination polymer, [Mn6(Ipa)6(ad)⋅6H2O] (1; Ipa = isophthalate ligand; ad = adenine), was synthesized by reacting hydrated manganese nitrate with isophthalic acid and adenine under solvothermal reaction conditions. Polymer 1 was characterized using single‐crystal X‐ray diffraction analysis and other techniques such as Fourier transform infrared spectroscopy, elemental analyses and powder X‐ray diffraction. The solid‐state structure of 1 confirmed the formation of a three‐dimensional framework structure based on Mn6 secondary building units. Phase purity of bulk 1 and its thermal stability were investigated. Polymer 1 was evaluated for its performance as a heterogeneous catalyst for the Henry (nitroaldol) reaction of nitromethane with several aldehydes. The recyclability of 1 and heterogeneity of the reaction were also explored. A plausible mechanism for such reaction is proposed. To the best of our knowledge, polymer 1 represents the first example of a Mn (II)‐ and adenine‐containing coordination polymer as well as the first example of a Mn (II)‐containing coordination polymer that has been employed for the Henry reaction.

“…Adenine, as an important naturally occurring nitrogen heterocycle present in nucleic acids [40], has multiple possible metal-binding modes [41][42][43]. It has been reported that adenine could coordinate with Zn [44], Au [45], Ag [46], Co [47] or Cu [48] to form CPs with diversified morphology and structure. However, most of the researchers just studied the structure of these materials, and very few have studied the encapsulating adaptability of CPs and the activity of guests after they were entrapped.…”

“…However, most of the researchers just studied the structure of these materials, and very few have studied the encapsulating adaptability of CPs and the activity of guests after they were entrapped. What is more, those CPs that have been reported were formed by harsh reaction conditions, complicated syntheses and with high cost [44][45][46][47][48].…”

In-Situ Self-Assembly of Zinc/Adenine Hybrid Nanomaterials for Enzyme Immobilization

et al. 2017

Abstract:In this study, a one-step and facile immobilization of enzymes by self-assembly of zinc ions and adenine in aqueous solution with mild conditions was reported. Enzymes, such as glucose oxidase (GOx) and horseradish peroxidase (HRP), could be efficiently encapsulated in Zn/adenine coordination polymers (CPs) with high loading capacity over 90%. When the enzyme was immobilized by CPs, it displayed high catalytic efficiency, high selectivity and enhanced stability due to the protecting effect of the rigid framework. As a result, the relative activity of Zn/adenine nano-CP-immobilized GOx increased by 1.5-fold at pH 3 and 4-fold at 70 to 90 • C, compared to free GOx. The immobilized GOx had excellent reusability (more than 90% relative activity after being reused eight times). Furthermore, the use of this system as a glucose biosensor was also demonstrated by co-immobilization of two enzymes, detecting glucose down to 1.84 µM with excellent selectivity. The above work indicated that in-situ self-assembly of Zn/adenine CPs could be a simple and efficient method for biocatalyst immobilization.
