Abstract and Figures

Two new cobalt‐based coordination polymers (CPs) based on two different benzimidazole carboxylic acid ligands, namely, {[Co(L¹)(H2O)2]2SiF6·(H2O)2}n (1) and {[Co(L²)(H2O)2]2SiF6·(H2O)2}n (2) (HL¹ = 2‐[1H‐imidazol‐5‐yl]‐1H‐benzimidazole‐6‐carboxylic acid and HL² = 2‐[1H‐imidazol‐2‐yl]‐1H‐benzimidazole‐6‐carboxylic acid), were synthesized via solvothermally method. Structural analysis revealed that CP‐1 featured a two‐dimensional planar structure, while CP‐2 exhibited a one‐dimensional chain structure. CP‐1 achieved a specific capacitance of 658.6 F g⁻¹ at a current density of 1 A g⁻¹ and retained good capacitance after charge–discharge cycling tests. In addition, both CP‐1 and CP‐2 showed good adsorption performance for the anionic dye Congo red (CR), and the maximum adsorption capacities were 1256 and 2985 mg g⁻¹, respectively.

ABSTRACT
Two new cobalt- based coordination polymers (CPs) based on two different benzimidazole carboxylic acid ligands, namely,
{[Co (L1)(H2O)2]2SiF6·(H2O)2}n (1) and {[Co(L2)(H2O)2]2SiF6·(H2O)2}n (2) (HL1 = 2 - [1H- imidazol- 5- yl]- 1H- benzimidazole- 6- carb
oxylic acid and HL2 = 2 - [1H- imidazol- 2- yl]- 1H- benzimidazole- 6- carboxylic acid), were synthesized via solvothermally method.
Structural analysis revealed that CP- 1 featured a two- dimensional planar structure, while CP- 2 exhibited a one- dimensional
chain structure. CP- 1 achieved a specific capacitance of 658.6 F g−1 at a current density of 1 A g−1 and retained good capacitance
after charge–discharge cycling tests. In addition, both CP- 1 and CP- 2 showed good adsorption performance for the anionic dye
Congo red (CR), and the maximum adsorption capacities were 1256 and 2985 mg g−1, respectively.
1 | Introduction
Azo dyes are widely used in the textile printing and dyeing in-
dustry due to their excellent affinity for fibers. However, due to
incomplete wastewater treatment processes in factories, large
amounts of dye- containing wastewater are discharged into the
environment, resulting in severe and widespread pollution is-
sues [1]. Cellular processes rely on the normal functioning of
DNA, and azo groups can severely interfere with DNA disso-
ciation and replication, leading to an increased risk of diseases
such as cancer and leukemia [2]. As a result, the treatment of
azo dyes has become a key research focus in the field of environ-
mental protection [3, 4]. Currently, traditional methods such as
adsorption and degradation are widely applied for the treatment
of industrial dyes, with adsorption emerging as the most prom-
ising approach due to its cost- effectiveness and energy efficiency
[5]. Therefore, developing new materials capable of effectively
removing organic dyes from water bodies is of great importance
for environmental protection [6].
With the advancement of technology, the demand for electrical
energy continues to grow, leading to a significant increase in the
installation of solar photovoltaic, hydropower, and wind power
systems [7]. However, these energy sources are inherently inter-
mittent, making it crucial to store electricity generated during
peak production periods and release it during peak demand to
significantly reduce resource consumption. Mainstream en-
ergy storage methods are currently divided into two categories:
mechanical energy storage, such as pumped hydro storage,
which converts electrical energy into gravitational potential
energy but suffers from substantial energy losses, and electro-
chemical energy storage (EES), which includes supercapacitors

Benzimidazole(s): synthons, bioactive lead structures, total synthesis, and the profiling of major bioactive categories
Article
Full-text available
  • Mar 2025
Benzimidazole, a fused bicyclic compound with benzene and pentacyclic 1,3-diazole moeities, has a simple aromatic heterocyclic structure. The moiety has become an indispensable anchor for the development of new pharmacologically active products, and has yielded several therapeutic agents with anticancer, antihypertensive, antimicrobial, antifungal and antiulcer effects. Benzimidazoles, as synthetically feasible and pharmacophoric synthons, have been relentlessly pursued for the preparation of new analogues and derivatives, and they have successfully developed into some of the most sought-after and vital pharmacophores for drug discovery. The use of varied substituents and differing patterns around the benzimidazole nucleus has provided a wide spectrum of biological activities. In addition, the benzimidazole moiety constitutes a building block for the production of several drugs, drug candidates, new chemical entities, and lead molecules. The importance of this nucleus for bioactivity, e.g., antibacterial, antitubercular, antidiabetic, anticancer, antifungal, anti-inflammatory, analgesic, antioxidant, antihistaminic, and antimalarial activity, has led us to take note and provide an overview of the synthetic development approaches for various benzimidazole derivatives together with their biological actions. This review is projected to further assist in the design and development of new benzimidazole-based compounds for new and optimized pharmacologically active products towards new drug-development strategies.

Hierarchical two‐dimensional Ti‐MOF derived from MXene for hybrid supercapacitor electrodes
Article

  • APPL ORGANOMET CHEM
Presently, two‐dimensional (2D) metal–organic framework (MOF) are drawing increasing attention in energy‐storage areas. However, more and complexed factors would affect the nucleation and growth of 2D MOFs, and subsequently affect the final performance. Particularly, it is important to control the coordination rate between ions and ligands. In this paper, MXene was directly used as titanium source to coordinate with an organic ligand to form Ti‐MOF sheets. To further boost the performance, mesopores were introduced in preparing 2D Ti‐MOF, constructing hierarchical porous Ti‐MOF@Ti3C2TX hybrids. Results showed that diffusion‐controlled behaviors play a dominant role over surface capacitive behaviors during the charge storage process of the hierarchical porous hybrids. A hybrid supercapacitor (HSC) assembled with the obtained HP‐Ti‐MOF@Ti3C2TX and activated carbon (AC) exhibited an energy density of 22.9 Wh kg⁻¹ at a power density of 850 W kg⁻¹ (1 A g⁻¹), and a power density of 4.25 kW kg⁻¹ at an energy density of 15.3 Wh kg⁻¹ (5 A g⁻¹). The present strategy is expected to provide design ideas for novel energy‐storage electrode materials.

Water‐Resistance‐Based S‐Scheme Heterojunction for Deep Mineralization of Toluene
Article
Full-text available
Deep mineralization of low concentration toluene (C7H8) is one of the most significant but challenging reactions in photocatalysis. It is generally assumed that hydroxyl radicals (⋅OH) as the main reactive species contribute to the enhanced photoactivity, however, it remains ambiguous at this stage. Herein, a S‐scheme ZnSn(OH)6‐based heterojunction with AlOOH as water resistant surface layer is in situ designed for tuning the free radical species and achieving deep mineralization of C7H8. By employing a combination of in situ DRIFTS and materials characterization techniques, we discover that the dominant intermediates such as benzaldehyde and benzoic acid instead of toxic phenols are formed under the action of holes (h⁺) and superoxide radicals (⋅O2⁻). These dominant intermediates turn out to greatly decrease the ring‐opening reaction barrier. This study offers new possibilities for rationally tailoring the active species and thus directionally producing dominant intermediates via designing water resistant surface layer.

Selective Separation of C8 Aromatics by an Interpenetrating Metal-Organic Framework Material
Article
  • Sep 2024
  • INORG CHEM
O-xylene (OX) is an important chemical raw material, but it is often produced in mixtures with other C8 aromatics. Similar physicochemical properties of the C8 isomers make their separation and purification very difficult and energy intensive. There is an unmet need for an adsorbent that would be effective for the separation of OX from the other C8 isomers. This work reports a three-dimensional interpenetrated metal–organic framework, SYUCT-110, that interacts with each of the single-component C8 isomers to form. The selectivity of C8 aromatic hydrocarbons was determined through liquid-phase batch uptake experiments. The results revealed that the selectivity order was OX > PX > MX > ethylbenzene (EB). The selectivity values were found to be 2.63, 1.58, 5.51, 3.71, 1.86, and 3.02 for OX/MX, OX/PX, OX/EB, PX/MX, MX/EB, and PX/EB, respectively. The adsorption capacity of OX was 71 mg/g. Grand Canonical Monte Carlo simulations were used to study the C8 adsorption sites, revealing that π···π interactions are the main reason for the observed adsorption selectivity. The adsorption energy calculation results also verified the selectivity of SYUCT-110 for the synthesis of OX.

Combined performance of circularly polarized luminescence and proton conduction in homochiral cadmium(ii)–terbium(iii) complexes
Article
  • Jan 2024
Multifunctional materials with proton conduction, circularly polarized luminescence (CPL) and a magneto-optical Faraday effect would provide a great opportunity for applications in luminescent, electrical, magneto-optical and optical–electronic smart devices. However, such types of multifunctional systems have rarely been reported. Herein, by introducing a chiral amine–phenol ligand, a pair of Cd(II)–Tb(III) enantiomers, [Cd2Tb(RR/SS-H2L)2(H2O)6](ClO4)3·2H2O (R-1 and S-1) [H2L = ((SS/RR)-cyclohexane-1,2-diylbis(azanediyl)-bis(methylene)-bis(2-methoxyphenol))], were obtained. R-1 and S-1 feature the homochiral molecules of trinuclear Cd2Tb structures, which contain abundant H-bonds to form three-dimensional (3D) supermolecular frameworks. They are chiral multifunctional materials showing strong Tb(III) characteristic emissions, a moderate proton conductivity of 1.17 × 10−4 S cm−1 at 333 K and 100% RH for R-1, CPL with a luminescence dissymmetry factor value of over 10−3 for R-1 and S-1 and a strong magneto-optical Faraday effect, and they are the first known materials simultaneously showing CPL, proton conduction and the Faraday effect.
