Herein, we fabricate a composite fluorescence sensor by integrating amine-functionalized carbon quantum dots (amine-CQDs) and a zirconium-based metal-organic framework (UiO-67) using a post-synthetic modification approach, and employ the resulting amine-CQDs@UiO-67 composite as a platform for highly selective and sensitive detection of 2,4-dinitrophenol (DNP). In particular, UiO-67 acts as an adsorbent for the selective capture and enrichment of DNP molecules, whereas amine-CQDs serve as functional monomers for selective and sensitive DNP sensing.
