Synthesis of Sm- and Eu- MOFs from 2,5-Diaminoterephthalic Acid for Selective Cationic Dye Adsorption and Luminescent Sensing of Nitroaromatic Compounds

Key Points

• This research aims to synthesize samarium (Sm) and europium (Eu) metal-organic frameworks (MOFs) to assess their efficacy in dye adsorption and nitroaromatic compound detection.
• Synthesis of Sm/Eu-MOFs using 2,5-diaminoterephthalic acid.
• Assessment of the MOFs for cationic dye adsorption.
• Evaluation of luminescent sensing capabilities for nitroaromatic compounds.
• Low detection limits for nitroaromatic compounds were achieved (0.34-0.36 ppm).
• Sm/Eu-MOFs exhibited excellent sensing ability.
• Demonstrated potential for selective dye adsorption and environmental pollutant detection.
