Abstract

Two phosphorous(V) corrole ligands, [5,10,15-pentafluorophenyl corrole] phosphorous (V), (PFCorr), and [10-(4-Trimhetylsilyphenyl)-5,15-dimesityl-corrole] phosphorous (V) (PCorr) were synthesized and tested as nitrite-sensitive ionophore. Fluorimetry studies on ligand sensitivity towards anions were carried out first in solution and then inside polymeric membrane optodes. The selective ligand fluorescence quenching was registered upon addition of growing amount of NO2--ions. The influence on the PFCorr optode response of the lipophilic sites functionalization was investigated. The sensor will be tested in natural (fresh and seawater) and fish farm waters in order to detect the effectiveness of nitrite assessment at recommended concentrations levels (less than 0.3 mg/L). © 2019 IEEE.
