Spectral and electrochemical anion sensing by a novel 5,10,15,20-tetrakis(R-substituted) porphyrin receptor (R = C6H4NHC(O)C5H4CoC5H5+PF6)

Abstract
A novel 5,10,15,20-tetrakis(R-substituted) porphyrin receptor molecule (R = C6H4NHC(O)C5H4CoC5H5 + PF6 )3 is prepared and is shown to spectrally and electrochemically sense halide, nitrate, hydrogen sulfate and dihydrogen phosphate guest anions.
