Abstract

A novel metal–organic framework (MOF) [Eu3L4(CH3COO) (H2O)7]·(CH3CN)5 (1) based on the ligand H2L (3′,5′‐di(1H‐1,2,4‐triazole‐1‐yl)‐[1,1′‐biphenyl]‐3,5‐dicarboxylic acid) has been synthesized by the hydrothermal method. A complete characterization of 1 was conducted, employing a range of techniques including crystallography, PXRD, SEM, FTIR spectroscopy, and TGA analysis. The fluorescence sensing behavior of 1 was examined in a solution of N,N‐dimethylformamide (DMF). The results demonstrated that 1 exhibited a pronounced "turn‐off" fluorescence phenomenon in the presence of caffeic acid (CA). Despite the interference of 11 potential substances, 1 was still capable of effectively recognizing CA. The luminescence intensity ratio of 1 showed a strong linear relationship with CA concentration in the range 0–5 μM. The Ksv value was 2.49 × 105 M−1. Additionally, the detection mechanism was studied using PXRD, SEM, UV–Vis, and fluorescence lifetime methods. [ABSTRACT FROM AUTHOR]
