A three‐dimensional Cu‐MOF ( XJU‐1 ) was synthesized based on 5‐((4‐[1 H ‐1,2,4‐triazol‐1‐yl]benzyl)amino)isophthalic acid ligand (H 3 L ), which showed excellent performance for Fenton‐like degradation of organic dyes (rhodamine B [RhB], methylene blue [MB], methyl orange [MO], violet [MV], congo red [CR], malachite green [MG], xylenol [XO]). The results demonstrated that could efficiently activate 2 O to achieve 100% removal RhB and MB with the initial concentration 10 mg/L under W light‐emitting diode ultraviolet light irradiation within 7 6 min, respectively. possible mechanism investigated via active species capture experiments, electron spin resonance (ESR) measurement, electrochemical analyses. hydroxyl radical (•OH) principal specie at whole process, whereas superoxide (•O − singlet oxygen 1 boost reaction mineralization dyes. Possible pathways were assumed testing intermediates. studies still maintained an efficiency after five cycles. In addition, iodine in cyclohexane solution investigated, had adsorption iodine, maximum capacity about 368 mg/g.

Two novel Cd-based noncentrosymmetric (NCS) chiral coordination polymers (CPs), [Cd2((S,S)-IBPhe)2(2,2′-bipy)2]·2H2O [Cd(S)] and [Cd2((R,R)-IBPhe)2(2,2′-bipy)2]·2H2O [Cd(R)] (IBPhe = isophthaloyl-bis-phenylalanine), have been synthesized through hydrothermal reactions. Cd(S) Cd(R) crystallize in the monoclinic polar space group, P21 (No. 4), exhibit rigid one-dimensional (1D) chain structures maintained by π–π interactions between organic ligands, as well C–H···π with adjacent chains. The solid-state photoluminescence data reveal intriguing blue light emission characterized a phosphorescence decay time of about 0.41 ms, attributed to ligand-to-ligand charge transfer effects. Impressively, these compounds high degree stability across various solvents pH conditions. Furthermore, their exceptional adsorption capacities for Congo red are evidenced maximum efficiencies 850.82 mg/g 817.71 Cd(R). These findings underline potential NCS diverse applications ranging from efficient dye removal enhanced photoluminescence.

A novel 2D coordination polymer with the formula {[bisopibiphenH2][Zn2(btc)2(H2O)2]}n (complex 1) was produced via solvothermal interaction of benzene-1,3,5-tricarboxylic acid (H3btc) ligand, 4,4′-bis((2-isopropyl-1H-imidazole-1-yl)methyl)-1,1′-biphenyl (bisopibiphen) compound, and Zn(II) ion. The structure final complex elucidated by single crystal/powder X-ray diffraction methods (SCXRD/PXRD), scanning electron microscopy–energy dispersive spectroscopy, Fourier transform infrared elemental analysis. According to results obtained from SCXRD method complex, it determined that formed central atoms a distorted tetrahedral geometry btc3– ligand. bisopibiphen compound used protonated acted as countercation within asymmetric unit, thus forming 3D supramolecular because interactions between layers. Additionally, topological thermal characteristics were examined. In later stage, adsorption performance 1 for methyl orange (MO) dye examined along influence various parameters. Kinetic isotherm studies also conducted explain nature MO process nature. this, experimental data well-matched pseudo-second order kinetics Langmuir model. maximum capacity 735.89 mg g–1 at 20 °C pH 4.0. These findings indicated could be promising effective adsorbent aqueous solutions.
