Abstract

Abstract : Novel metal–organic frameworks have been constructed based on fluorescent mixed ligands, which can be employed as efficient sensors. Abstract : In this study, by employing mixed organic ligands through rational design and metal ions as the initial reactants, a series of novel metal–organic frameworks (AHU-TW1 to 6 ) were synthesized by a solvothermal method. Herein, accessible Lewis base sites originating from organic ligands within MOFs act as functional sites that can interact with the analyte possessing protons and then lead to obvious variations in the fluorescence spectra. Due to their superiority, AHU-TW1, 3, 4 and6 are able to recognize trinitrophenol (TNP) with high sensitivity and a low detection limit.
