We successfully synthesized two new metal coordination polymers [Cd3(bdc)3(L)3(H2O)3]n (1) and [Co(tda)(L)]n (2) (H2bdc = 1,2-benzenedicarboxylic acid, H2tda = 2,5-thiophendicarboxylic acid, and L = 3,5-bis(benzimidazol-1-yl)pyridine), which were then characterized by IR, and elemental, X-ray powder diffraction, and X-ray single-crystal diffraction analysis. Complex 1 possesses a uninodal three-connected hcb Shubnikov hexagonal plane net with {63} topology. Complex 2 features a three-connected topological net with {82·10} topology (so-called ‘tongue-and-groove’ structure). A typical T-shaped molecular bilayer motif, which has rarely been reported previously, was successfully constructed by strategically selecting H2tda as the second ligand. In addition, the solid-state photoluminescent spectra of 1 and 2 were measured at room temperature.

In this study, lanthanide elements (Ln3+) and 2,3,5,6-tetrafluoro-1,4-benzenedicarboxylic acid (TFBDC) based metal-organic frameworks (MOFs) were synthesized by precipitation and diffusion-controlled precipitation methods. Powders insoluble in aqueous media and polar solvents were obtained. The microstructure and properties of Ln3+ MOFs were evaluated and discussed. X-ray diffraction (XRD) analysis, infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and fluorescence spectroscopy (FLS) were carried out to characterize Ln3+ MOF's crystallinity, the microstructure, chemical composition and optical properties.

Metal-organic frameworks (MOFs) composed by coordination bonds between metal ion with organic linker has a uniform combination of micro and mesoporous structures has been used for several application including battery supercapacitor hybrid. (BSH). In BSH, MOF offer several advantages including high surface area, porous, and structure tunability. This paper reports the synthesis of ternary MOF of copper (Cu), nickel (Ni) and cobalt (Co) with 1,4-benzenedicarboxylic acid. The Co/Cu/Ni-MOF is synthesized using hydrothermal method at 160 °C for 12h and further develop as a BSH electrode. The physicochemical properties of MOF were characterized using FESEM, FTIR, XRD, BET and the electrochemical properties were evaluated using cyclic voltammetry (CV), charge-discharge cycling (CDC) and electrochemical impedance spectroscopy (EIS). Electrochemical analysis indicated that the MOF has high specific capacitance (CS) of 591 F g-1 at a current density of 1 A g-1 and 519 F g-1 at scan rate of 2 mV s-1, and possess low series resistance (RS) of 0.44 Ω and equivalent distributed resistance (Rd) of 1.07 Ω.
