Ratiometric fluorescent sensor based on metal-organic framework for selective and sensitive detection of CO32

Carbonate ion (CO32-) is an anion essential for the maintenance of life activities and is of great importance to human health. Here, a novel ratiometric fluorescent probe Eu/CDsUiO-66-(COOH)2 (ECU) was prepared by introducing europium ions (Eu3+) and carbon dots (CDs) into the UiO-66-(COOH)2 parent framework under the guidance of a post-synthetic modification strategy and used for the detection of CO32- ion in the aqueous environment. Interestingly, when CO32- ions were added to the ECU suspension, the characteristic emission of carbon dots at 439 nm was significantly enhanced, while the characteristic emission of Eu3+ ions at 613 nm was reduced. Therefore, the detection of CO32- ions can be realized through the peak height ratio of the two emissions. The probe had a low detection limit (about 1.08 μM) and a wide linear range (0-350 μM) for the detection of carbonate. In addition, the presence of CO32- ions can cause a significant ratiometric luminescence response and resulted obvious red-to-blue color shift of the ECU under UV light, which will facilitate visual analysis by the naked eye.
