What is A fluorescent dual-emissions UiO-66-NH2@TpTt-COF core-shell composite for sensitive and optosmart sensing of tetracycline about?
Tetracycline residues are seriously hazardous to environment, it’s urgent to develop sensors to detect tetracycline for environmental monitoring. A fluorescence sensor based on dual-emissions UiO-66-NH2@TpTt-COF (donate as UNT) composite is constructed by an interfacial growth method for detecting tetracycline. The import of UiO-66-NH2 attenuates the aggregation-caused quenching (ACQ) of TpTt-COF, which endows UNT emitting strong dual-emissions of 452 nm and 575 nm. Tetracycline is recognized by UNT through π-π stacking and interacts with triazine N and deprotonated O of UNT through intermolecular hydrogen bonds. These interactions impede the excited state intramolecular proton transfer (ESIPT) and intramolecular charge transfer (ICT), and promote the photoinduced electron transfer (PET), inducing synchronous fluorescent quenching of the dual-emissions of UNT. The synchronous response of UNT enhances the specificity and displays excellent sensitivity toward tetracycline with a detection limit of 7.4 nmol/L. UNT is applied for the detection of tetracycline in soil and river water with recoveries of 92.96–98.44% and 88.58–104.31%, respectively. An optosmart sensing system has also be
