Abstract

A Silicon corrole complex has been utilised as a novel sensing material for the development of optode for fluoride ion detection. The fluoride binding induced UV-visible spectral changes exploited for the anion detection. The corrole complex was deposited onto paper strips from THF solution. The corrole spots changed from red pink to green color upon fluoride exposure. The color changes can be visually appreciated down to a fluoride ion concentration of 10 -5 mol/L.
