Redox-active chromophore grafted microenvironment in metal-organic framework recognizes aromatic amine isomers

Key Points

• The aim is to evaluate the ability of a redox-active chromophore within a metal-organic framework to distinguish aromatic amine isomers.
• Grafting a redox-active chromophore into a Zr-based metal-organic framework (MOF-808)
• Characterization of the resulting fluorescent porous solid
• Testing the discrimination capability between different aromatic amine isomers
• The modified MOF-808 exhibited fluorescence
• Successfully discriminated between various aromatic amine isomers
• Demonstrated enhanced sensitivity and selectivity in recognizing specific isomers
