Xing, Kai; Fan, Rui-Qing; Liu, Xiao-Yuan; Gai, Shuang; Chen, Wei; Yang, Yu-Lin; Li, Jing published an article in 2020, the title of the article was A self-calibrating dual responsive platform for the sensitive detection of sulfite and sulfonic derivatives based on a robust Hf(IV) metal-organic framework.Name: Pyridine-3-sulfonic acid And the article contains the following content:
A robust hafnium-based metal organic framework, Hf-PBTA, with sensitive and self-calibrating dual-emissive fluorescence response towards sulfite and sulfonic derivatives, including antibiotic sulfamethazine, has been developed, which shows fast detection of sulfite ions at a concentration as low as 76 ppb. The opposite response tendency from two radiative pathways towards aromatic sulfonic mols. and sulfite anions stems from the synergistic effect of the pyridine protonation effect, π-π stacking interaction and intramol. twist motion. The experimental process involved the reaction of Pyridine-3-sulfonic acid(cas: 636-73-7).Name: Pyridine-3-sulfonic acid
