Metal organic frameworks (MOFs) have become highly promising materials for a wide range of applications because of their distinct characteristics and structural adaptability. The utilization of MOFs in composite materials has the potential to expand their range of applications. This study focuses on the development of an iron-doped zinc metal organic framework (Fe@Zn-MOF-2) using a previously synthesized zinc-based MOF. The efficacy of Fe@Zn-MOF-2 was investigated for sensing Gd3+ and acetophenone, as well as its potential as an electrode material for energy storage devices. The photoluminescence sensing experiments showed a significant improvement in the efficiency of sensing Gd3+ and acetophenone when using the Fe@Zn-MOF-2 composite. The composite achieved sensing efficiencies of 97.73% and 98.45%, respectively, which were higher than the efficiencies of 33.25% and 35.71% observed when using only the Zn-MOF. Furthermore, both materials exhibited substantial disparities in specific capacitance when examined as energy storage electrodes through the methods of cyclic voltammetry (CV), galvanostatic charge–discharge (GCD) analysis, and electrochemical impedance spectroscopy (EIS). Fe@Zn-MOF-2 exhibits a specific capacitance of 318.09 F g−1, while the Zn-MOF has a specific capacitance of 33.00 F g−1. Fe@Zn-MOF-2 exhibits a specific capacitance retention of 94.57% after undergoing 2000 cycles in cyclic voltammetry. The results emphasize the capability of Fe@Zn-MOF-2 for versatile uses in sensing and energy storage. [ABSTRACT FROM AUTHOR]

A coordination polymer (CP) based on Co(II), {[Co(Ox)(H2O)3] · 2H2O}n (KA@CP2_ARS), has been synthesized using 1,3,5-tris[(1H-imidazol-1-yl)methyl]benzene (Timb) and potassium oxonate (OxK) at room temperature which was examined by single-crystal X-ray diffraction. KA@CP2_ARS contains a one-dimensional (1-D) helical chain that is extended through hydrogen-bonding interactions to form two-dimensional (2-D) and three-dimensional (3-D) supramolecular networks. KA@CP2_ARS demonstrates highly selective luminescent performance for IPA, Co2+, MnO4–, and uric acid with detection limits of 0.214, 0.16, 0.076, and 0.65 ppm, respectively, among the screened analytes. KA@CP2_ARS displays strong photocatalytic activities for degrading 88.6% of methyl violet dye under ultraviolet irradiation. [ABSTRACT FROM AUTHOR]

A Zn(II)-based polyrotaxane 1D coordination polymer, {[Zn(Or)(Bimb)(H2O)]2·2H2O}n, 1 (Or = orotate; Bimb = 1,4-bis[(1H-imidazol-1-yl)methyl]benzene), has been synthesized. 1 provides for luminescent sensing of acetone, Fe3+, MnO4–, nitrofurantoin (NFT), uric acid (UA), and sucrose. The coordination polymer displays exceptional intensity quenching of ∼96.1% with 200 mg/dl of sucrose in aqueous solution. In addition, the reactivity of 1 to photocatalytically degrade the organic dye methylene blue (MB), a hazardous organic pigment, was established. 1 was able to degrade the dye due to the generation of reactive oxygen species.
