A simple and efficient method has been developed for the synthesis of benzoxazole derivatives. In the first step, 2-aminophenols reacted with various aldehydes in the presence of titanium supported nano-silica to produce an imine intermediate. Then the imine was oxidized to get the final azole compounds. Eleven derivatives were synthesized (c)-(m) via this simple and environmentally friendly procedure with high yields. The simple methodology (only 2 steps) with high yields for the reactions and easy procedure are the advantages of the newly developed method. The identification and characterization of all the synthesized compounds were confirmed by melting point, thin layer chromatography, FT-IR, H-1 NMR and C-13 NMR spectral data. Also elemental analysis was applied for five compounds. All the compounds were screened for antimicrobial activity by broth microdilution methods as recommended by CLSI. Of the tested compounds 2-(2,4-dichlorophenyl)-1,3-benzoxazole (g), and 2-( 4-chlorophenyl)-1,3-benzoxazole (f) inhibited the growth of all examined fungi, while 2-(4-nitrophenyl)-1,3-benzoxazole (c) exhibited inhibitory activities only against the tested yeasts.

Specifically, visually, and quantitatively monitor copper ion (Cu2+) is critical in the area of biological and environmental detection. Herein, a ratiometric fluorescent probe with benzoxazole appended xanthenes skeleton was constructed and further employed to monitor Cu2+ in Hela cells, real water samples, and test strips. An easily distinguishable colorimetric (colorless to red) and fluorescence (green to red) change could be observed by naked eye under the portable UV lamp (365 nm) and the changes could be recovered by adding S-2. Furthermore, electrospinning technique was employed to fabricate a probe composited fluorescent sensing film (PMMA) for realizing the visual and recyclable monitoring of Cu2+, indicating that the probe-composited fluorescent sensing film has great potential for on-site and naked-eye detection of Cu2+ in practical.

New discoveries in chemical research and development in 2021. As an important bridge between the micro, chemistry is one of the main methods and means for humans to understand and transform the material world.

Herein, we fabricated two types of electrospun membrane using: 1) sulfonated poly (arylene ether sulfone), which needs chemical cross-linking to increase its mechanical strength, and 2) thermally rearranged poly (benzoxazole-co-imide), which is mechanically robust while requiring the hydrophilic coating. With a high porosity and low structure parameter of the support layer, two thin film composite (TFC) membranes were fabricated via interfacial polymerization on the support layer using 1,3,5-bezenetricarbonyl trichloride (TMC) and m-phenylene diamine (MPD) monomers. Chlorine modification using NaOCl solution was applied to two TFC membranes (denoted as XBPSH-TFC-Cl and XPBO-TFC-Cl, respectively) to improve water permeability (A) of the polyamide selective layer, while maintaining decent salt rejection values (R). As a result, the highly efficient XPBO-TFC-Cl achieved a peak power density of 26.6 W.m(-2) at 21 bar using 1 M NaClaq and deionized (D.I.) water as draw and feed solutions, respectively. According to the modeling results, XPBO-TFC-Cl was less affected by the adverse phenomena (such as concentration polarization and reverse salt permeation), and showed lower performance reduction for various feed sources compared to XBPSH-TFC-Cl. These results demonstrate the potential of the next generation TFC membranes, which are commonly used for power generation and liquid separation.

Membrane and membrane process have been considered as one of the most promising technologies for mitigating CO2 emissions from the use of fossil fuels. In this paper, recent advances in polymeric membranes for CO2 capture are reviewed in terms of material design and membrane formation. The selected polymeric materials are grouped based on their gas transport mechanisms, i.e., solution-diffusion and facilitated transport. The discussion of solution-diffusion membranes encompasses the recent efforts to shift the upper bound barrier, including the enhanced CO2 solubility in several rubbery polymers and novel methods to construct shape-persisting macromolecules with unprecedented sieving ability. The carrier-bearing facilitated transport membranes are categorized based on the specific CO2-carrier chemistry. Finally, opportunities and challenges in practical applications are also discussed, including post-combustion carbon capture (CO2/N-2), hydrogen purification (CO2/H-2), and natural gas sweetening (CO2/CH4).

The presence of benzoxazole moiety in most of the heterocyclic compounds is well reported. The present literature review mainly highlights the novel synthetic transformation and describes the biological potential of most of the heterocyclic compounds by virtue of presence of benzoxazole framework. Most of the researchers have revealed that benzoxazole derivatives exhibit significant antibacterial, anti-inflammatory, antifungal, anticancer, analgesic, antiviral, anti-tubercular, and anthelmintic activities. Benzoxazole moieties also act as tyrosinase inhibitor and cholesterol ester transfer protein inhibitor.

Six benzoxazole-terminated mesogenic compounds with fluoro substituent at different positions were prepared and their properties investigated. The compounds give a high birefringence (Delta n similar to 0.45) and a large-dielectric anisotropy (Delta epsilon similar to 26), indicating a possible application in liquid-crystal mixture as a dopant to enhance performance of the host mixture. In accordance with conventional high Delta n liquid crystals containing triple carbon-carbon bonds, lateral fluoro substituents and terminal groups can alter the Delta n and Delta epsilon of benzoxazole-terminated liquid crystals. Meanwhile, some parameters such as dipole moment, polarisability, dihedral angles are calculated with density functional theory (DFT) methods to relate to the experimental Delta n and Delta epsilon. It is noted that the introduction of the benzoxazole unit is an effective method to enhance Delta n and Delta epsilon values of the rodlike molecule, this is ascribed to its pi-conjugated benzene-fused heterocycle and large dipole moment.
