A multifunctional fluorescence MOF material: Triple-channel pH detection for strong acid and strong base, recognition of moxifloxacin and tannic acid

A luminescent MOF 1 was synthesized based on 4-(2-aminopyrimidine-5-yl)benzoic acid. 1 possesses the triple-channel pH sensing ability for strong acid, strong base and weak acid by change of emission wavelength and intensity. 1 can also detect antibiotic moxifloxacin and polyphenol compound tannic acid with LOD at the 10 ppb level.
