Optical properties evaluation on
d andf metal ions based dicarboxylic MOFs for pollutant sensingHere, we have synthesized
d andf metal ions, i.e., iron (III) and europium (III) chloride hexahydrate-based dicarboxylic metal-organic framework (MOF) with common organic linker benzene-1,4-dicarboxylic acid, using solvothermal method under certain experimental conditions. The synthesis and structural validation of dicarboxylic MOFs have been confirmed using Powder X-ray diffraction techniques, scanning electron microscopy, infrared and absorption spectroscopy. In line of the comparative study ond andf metal ions based dicarboxylic MOFs, luminescent features has been confirmed in different solvents using photoluminescence spectroscopy. Importantly, optical sensing of pollutant using Eu-MOF and Fe-MOF has been demonstrated in chloroform. Notably, the luminescence quenching mechanism has been recognized towards energy competition between Eu-MOF and analyte. The observedf –f transitions effective support makes ideal detection of selected pollutant, i.e., nitrobenzene using Eu-MOF over Fe-MOF. Finally, $R^2$ = 0.9379 with limit of detection of 0.100 ppm was noted using Eu-MOF for pollutant detection.
