Fluorescent Zr(IV) Metal-Organic Frameworks for the Rapid and Sensitive Detection of Acidic Nitrophenols in Water.

ABSTRACT: Nitroaromatic compounds (NACs) are widely used industrial chemicals, recognized as both environmental pollutants and explosive hazards. Optical sensors are gaining increasing research ground as they offer a platform for the rapid and efficient in-field detection of NACs. Herein, we report the rational design and synthesis of three new fluorescent metal-organic frameworks (MOFs) based on Zr(IV) and structurally analogous to UiO-66, with the assigned formula {Zr₆O₄(OH)₈(H₂O)₄(L)_1-x(NH₂bdc^2-)_x}. The incorporation of strongly fluorescent ligands 2-((2-methoxybenzyl)amino)terephthalic acid (L-2), 2-((3-methoxybenzyl)amino)terephthalic acid (L-3), and 2-((4-methoxybenzyl) amino)terephthalic acid (L
