Design ands ynthesis of stable, active and cost-effective electrocatalystf or water splitting applicationsi sa n emerging area of research, given thed epletion of fossil fuels. Herein, two isostructuralN i II redox-activem etal-organic frameworks (MOFs) containing flexible tripodal trispyridyl ligand (L)a nd linear dicarboxylates such as terephthalate (TA) and 2-aminoterphthalate (H 2 NTA) are studied fort heir catalytic activity in oxygen evaluation reaction( OER). The 2D-layered MOFs form 3D hydrogen bonded frameworks containing one-dimensional hydrophilic channels that are filled with water molecules. The electrochemical studies reveal that MOFs display an efficient catalytic activity towards oxygen evolutionr eactioni na lkaline conditions with an overpotential as low as 356 mV.F urther,t hese 2D-MOFs exhibit excellenta bility to adsorb water vapor (180-230 cc g À1 at 273 K) and CO 2 (33 cc g À1 at 273 K). The presence of hydrophilic functionality in the frameworks was found to significantly enhancet he electrocatalytic activity as well as H 2 Os orption.Supporting information and the ORCID identification number(s) for the author(s) of this articlecan be found under: https://doi.

“…This correlates the above findings of interesting intermolecular interactions and extended supramolecular framework of 1 , which prompted us to explore the dyes adsorption and desorption studies by employing 1 . The adsorption of dyes from wastewater has gained considerable importance from an environmental prospective . In this regard; Congo Red (CR), Eosin B (EO), Chicago Sky Blue (CSB), Methyl Orange (MO) and Crystal Violet (CV) were chosen as model pollutants to evaluate the adsorption ability of 1 .…”

A new Cd(II) based coordination polymers {[Cd(Azopy)(H2O)4]⋅(NDC)}n (1) has been designed and synthesized by using 4,4′‐Azopyridine (Azopy), and 2, 6‐Naphthalene dicarboxylic acid (NDC) as a linker at ambient condition. The bulk purity of the 1 was analysed by powder X‐ray diffraction (PXRD) analysis, infrared spectroscopy and further confirmed by single crystal X‐ray studies. The crystal structure of 1 revealed a polythreading feature where each 2, 6‐naphthalene dicarboxylate unit are trapped between two one‐dimensional (1D) chain of [Cd(Azopy)(H2O)4]∞ via strong hydrogen bonding interactions. The hydrogen bonding and π⋅⋅⋅π stacking interactions of 1 play a crucial role in the formation of the infinite 3D‐layered supramolecular network. Furthermore, the reduction of nitro‐aromatics to their corresponding amines was performed using green hydrogen source such as D‐glucose in H2O solvent at room temperature. Additionally, the dye adsorption studies revealed that 1 can adsorb Congo Red (CR) dye in a very short span of time. The kinetic study result reveals that the adsorption of CR for 1 is fitted well (R2 =0.996) with a pseudo‐second‐order kinetic model. Moreover, photoluminescence of 1 shows emission in the blue region with λmax at 395 nm and 408 nm at room temperature in the solid state. 1 shows multi‐facet behaviour such as facile synthesis, luminescent nature in solids‐state, emerged as a heterogeneous dye‐adsorbent and catalyst which makes it easy to scaled‐up.

Three metal‐organic frameworks {[Cd(L)(glu)]⋅3 H2O}∞ (1), {[Cd2(L)2(adi)2]⋅5 H2O}∞ (2) and {[Cd(L)(sub)]⋅3 H2O⋅DMA }∞ (3) (L=pyridine‐3,5‐bis(5‐azabenzimidazole), H2glu=glutaric acid, H2adi=adipic acid and H2sub=suberic acid) were obtained under solvothermal conditions. Complex 1 shows a 2D (4,4) network constructing of Cd2‐glu and Cd‐L chains. Complex 2 presents a 2‐fold interpenetrating 3D framework with pcu topology. Complex 3 is a 3D framework with cds topology. Three complexes with versatile structures were obtained by changing aliphatic dicarboxylate ligands with different lengths based on a N‐rich ligand. Moreover, the fluorescence measurements indicate that complex 1 is a good multifunctional chemosensor for the detection of Cr2O72− and MnO4− anions by fluorescence quenching effect, and ethylenediamine by fluorescence enhancement effect, with detection limits of 1.196 ppm, 0.551 ppm and 64.572 ppm, respectively. Both complexes 2 and 3 can selectively sense Cr2O72− anion with detection limits of 1.126 ppm for 2 and 0.831 ppm for 3 by a fluorescence quenching effect.
