“…They stand out among polymer materials owing to their properties, for instance, large surface area, adjustable structure and high porosity (Furukawa et al, 2010;Zhou et al, 2012;Long & Yaghi, 2009). Extensive efforts have been devoted to synthesizing and investigating novel MOFs, not only because of their intriguing structures and distinctive topologies, but also due to their promising applications as functional materials in many fields, such as luminescence (Cui et al, 2012a,b;Hu et al, 2014Hu et al, , 2020Liu & Dai, 2018;Yu et al, 2020;Singh, 2018Singh, , 2019Singh & Bhim, 2016), drug delivery and release (Chen et al, 2018a,b;Zheng et al, 2016;Pan et al, 2020), gas storage and separation (Li et al, 2009(Li et al, , 2017Lee et al, 2009;Gong et al, 2009;Taylor et al, 2018), catalysis (Parmar et al, 2018;He et al, 2018;Wu et al, 2019;Pan et al, 2019;Singh & Bharadwaj, 2013), supercapacitors (Liu et al, 2020) and magnetism (Cheng et al, 2010;Tian et al, 2015;Xu et al, 2003). As is well known, the construction of stable coordination frameworks is mainly dependent on a combination of several factors, such as the organic ligand, solvent, metal centre, pH value, temperature, and so on (Mu et al, 2012;Sun et al, 2013;Bu et al, 2002;Liu et al, 2007;Zhang et al, 2009;Manna et al, 2014).…”

Seven new metal–organic frameworks (MOFs), namely, [Zn2(L 1)(H2O)3] n (1), [Zn2(L 1)(dib)(H2O)2] n (2), {[Zn2(L 1)(4,4′-bipy)(H2O)2]·H2O} n (3), [Cd2(L 1)(1,10-phen)] n (4), [Ni2(HL 1)(4,4′-bipy)(μ3-OH)(μ2-H2O)] n (5), {[Co4(L 1)(4,4′-bibp)3]·(4,4′-bibp)3} n (6), and [Co2(L 2)(4,4′-bibp)2(H2O)] n (7), where H4 L 1 and H4 L 2 are semi-rigid 3-(3,5-dicarboxylphenoxy)phthalic acid and 4-(3,5-dicarboxylphenoxy)phthalic acid, respectively, and 4,4′-bipy is 4,4′-bipyridine, dib is 1,4-bis(1H-imidazol-1-yl)benzene, 1,10-phen is 1,10-phenanthroline and 4,4′-bipb is 1,4-bis(pyridin-4-yl)benzene, have been prepared under solvothermal conditions with ZnII, CdII, CoII and NiII ions in the presence of auxiliary N-donor ligands. The crystal structures and photoluminescence and magnetic properties of these compounds have been investigated. Compound 1 displays a 3,4,6-connected two-dimensional (2D) topology with a Schläfli symbol of (42.5)2(43.52.7)(45.56.63)2, and the 2D structure was further assembled to form a three-dimensional (3D) framework by intermolecular O—H...O hydrogen bonds. Compound 2 features a novel 3,3,4-connected structure and the point symbol is (4.102)(4.6.84)(62.8). Compound 3 exhibits a 3,4,6-connected 3-nodal net having a 3,4,6 T53 type topology, with the point symbol (4.62)2(42.64)2(42.68.82.103). Compound 4 shows a 2D→3D supramolecular structure formed by π–π stacking interactions. Compound 5 possesses a 3D framework with a tfz-d net topology. Compounds 6 and 7 are constructed from the same auxiliary ligand and metal salt at the same temperature, but with different main ligands and exhibiting different topologies. Compound 6 presents a 3D 4,6-connected topological network with a Schläfli symbol of (3.44.6)(32.44.56.63), while compound 7 has a 3D topological network with a Schläfli symbol of (412.616). Magnetic analyses indicate that compounds 5 and 7 show weak antiferromagnetic interactions.

“…MOF materials, also known as coordination polymers, are porous crystalline structures formed by metal ions that are coordinated, or form a dative bond, with organic ligands. [47,48] The fabrication of MOF materials is done through a bottomup approach where metal ions and organic ligands self-assemble into crystalline structures through chemical synthesis. The chemical synthesis of these materials allows for doping, the encapsulation and formation of composite material structures with metals and MOs.…”

Gas sensing technology platforms have allowed for the improvement of crucial industrial processes and the decreased emissions of environmentally harmful gases that have led to deleterious outcomes. Industries where gas control has become critical are petrochemical, refinery, food and beverage, and power generation. These industries utilize gases such as ethylene, sulfur, carbon dioxide (CO 2 ), and oxygen (O 2 ) to produce gasoline, carbonated beverages, and electricity. [1] During various processes, harmful gases such as carbon monoxide (CO), CO 2 , sulfur dioxide (SO 2 ), and nitrogen dioxide (NO 2 ) and volatile organic compounds (VOCs) such as ethanol (C 2 H 5 OH), acetone (CH 3 COCH 3 ), toluene (C 7 H 8 ), and acetylene (C 2 H 2 ) can be emitted. [2][3][4][5][6] The emission of these environmentally toxic gases and VOCs from both industrial processes and automobiles has been linked to the nitrous oxides (NO x ), CO, and hydrocarbon emissions responsible for acid rain in the 1960s. Legislation was introduced to address and mitigate this acidic precipitation and the emission of environmentally toxic gasses by requiring the use of gas sensors and catalytic converters. [2] Gas sensing technology can be found in two leading commercial platforms: electronic (lambda sensors) and optical (nondispersive infrared (NDIR) sensors and optrodes). Lambda sensors are made with electrolytes or gas-sensitive films that exploit the ionic conductivity of electrolytes or the adsorption of gases and bonding of hydroxyl groups on metal oxide (MO) materials. State-of-the-art, automotive lambda sensors, also known as "automotive oxygen sensors," use a solid yttria-stabilized zirconia (YSZ) electrolyte in wideband sensor design geometries. The wideband sensor design was adapted from the early narrowband YSZ sensor design that utilized a simple Nernst cell. The wideband sensor design offers improved sensor linearity when compared to the narrowband designs across a wide range of air-to-fuel ratio values. Though the electrolytic lambda sensors' physical design has changed in previous years, the sensor has not seen an improvement in terms of electrolytic materials.Lambda sensors have also been based on gas-sensitive oxide films, instead of electrolytes, that employ the use of MO materials. MO materials include a wide range of oxidized transitional metals. These MOs undergo electronic changes when gases or VOCs are chemisorbed or bound to hydroxyl groups on the material's surface, thereby increasing or decreasing the MO's resistivity. The gas-material interaction only occurs at high temperatures, called the "activation temperatures," required by the MO.High activation temperatures are common in both electrolytic and MO gas sensors. Bringing the electrolytic and MO gas sensors to these high temperatures requires electronic heater elements. The reduction of the activation temperature of a lambda sensor can be achieved by using promoter materials and catalytic metals. Some material platforms, such as metal-organic frameworks (MOFs), are als...

“…[190][191][192] A basic condition for these new applications is the ability to move electronic charge from a conductive electrode to a MOFanchored light harvesting, sensing, or catalytic site through a porous structure (and in the opposite direction). [193,194] Farha et al reported the modulation of charge transportation rates using host-guest chemistry in MOF films, demonstrating that the kinetics of site-to-site charge hopping and, generally, the total redox conductivity of an FC-based MOF can be changed (up to 30-fold) by coupling electron exchange to the oxidationstate-dependent organization of entrance complexes between channels connected to metallocenes and cyclodextrin. The obtained results suggested that studies of MOFs as ingredients of photoelectrochemical and electrochemical energy transformation systems can benefit from this novel procedure of charge-transport attribute tuning.…”

Ferrocene and its derivatives, especially ferrocene-based coordination polymers (Fc-CPs), offer the benefits of high thermal stability, two stable redox states, fast electron transfer, and excellent charge/discharge efficiency, thus holding great promise for electrochemical applications. Herein, we describe the synthesis and electrochemical applications of Fc-CPs and reveal how the incorporation of ferrocene units into coordination polymers containing other metals results in unprecedented properties. Moreover, we discuss the usage of Fc-CPs in supercapacitors, batteries, and sensors as well as further applications of these polymers, for example in electrocatalysts, water purification systems, adsorption/storage systems.
