“…A similar effect is found for the synthesis of FeÍCNÍCo MCNPs in cationic reverse micelle solution of cetyltrimethylammonium halides [CTAX, X = Br and Cl]. 81 The color of the reaction mixture dramatically changes from red to green with increasing reaction time (Figure 24) accompanied by a change in XRD patterns, which is due to the temporal evolution of the crystal structure from the fcc structure with Co II (O h ) sites to the disordered structure containing Co II (T d ) sites triggered by a cetyltrimethylammonium cation as a bulky capping ligand. These findings are examples of the surface effect of MCNPs.…”

This account reviews the chemical synthesis of inorganic nanoparticles stabilized by an organic shell layer and the investigation of their specific characteristics. Consideration of design and construction of organicÍinorganic hybrid nanoparticles by wet process is indispensable in order to exploit the unprecedented nature resulting from the fusion of both organic and inorganic traits. In a series of studies, two synthetic parameters were the center of focus: physical construction of the inorganic core and the chemical constituents introduced. External stimuli such as electric fields or solvent polarity can be utilized to transform the characteristics of nanoparticles when redox active or liquid crystalline molecules as an organic shell are attached to the surface of an inorganic nano-core. In another case, the catalytic activities of nanoparticles are controllable by modifying the crystal faces and the surface area of the inorganic cores in connection with shape and size. Novel nanomaterial has also been fabricated by choosing a metal coordination polymer as a core, leading to the first isolation of alkyl chain-stabilized metal coordination nano-polymers (MCNPs). The compounds are listed as Pt nano-cubes, size-selected Au nanoparticles, metal hexacyanoferrate MCNPs, and metal nanoparticles functionalized by biferrocene, anthraquinone, and triphenylene derivatives. Synthetic procedures and remarkable characteristics are demonstrated.

“…[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. [134][135][136][137] While the above examples highlight the rich coordination modes of Ade leading in the formation of highly porous bio-MOFs, nucleobases such as Gua and their derivatives, are known to form Gquartet, and G-quadruplexes structures which have emerged as powerful tools for developing nanoscale porous materials and devices. [138][139][140][141][142][143][144][145] Verma et al reacted N9-allylguanine and N9-propargylguanine with cupric halides to form three structures ranging from discreet trinuclear motif to a mixed valence coordination polymer (Table 3, entry 16).…”

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 a result, metal hexacyanoferrates nanoparticles modified electrodes have also been investigated [12][13][14][15][16][17][18][19][20][21][22][23][24]. Baioni et al [12,13] synthesized copper hexacyanoferrate nanoparticles and the nanoparticles were immobilized on the surface of ITO electrodes by the method of self-assembled layers.…”
