Dual-State Red-Emitting Zinc-Based MOF Accompanied by Dual-Mode and Dual-State Detection: Color Tonality Visual Mode for the Detection of Tetracycline

ACS Applied Materials & Interfaces, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 13, 2024

Red-emitting metal-organic frameworks (MOFs) are still mostly based on the use of lanthanides or functionalization with red fluorophores. However, production transition-metal-based MOFs red-emitting is scarce. This work reports synthesis a novel dual-state Zn-based MOF (denoted as UoZ-7) capability to detect target molecules in dual state, solution, and solid paper. UoZ-7 gives strong emission when excited solution state 365 nm ultraviolet (UV) lamp irradiation. Coordination-induced mechanism for enhancement restriction intramolecular rotation occurred ligand within framework structure. was successfully used tetracycline (TC) using dual-mode detection, fluorescence-based ratiometry, color tonality, TC adsorb surface, yellow-greenish emerges due aggregation-induced between UoZ-7. Concurrently, inner filter effect diminishes The detection platform provides simple reliable fast method on-site various environmental biomedical applications. Moreover, will have further luminescence-based
