Deprotonation, Water content in organic solvent
A simple chromogenic system based on 1-fluoride was developed to determine water content in organic solvent. This system utilized deprotonation and protonation of the anion receptor 1. The water content evaluated from this system gave close value to the real water content in the range of 0 to 0.35% in acetonitrile and 0.2 to 0.5% in DMSO. Therefore, protonation and deprotonation phenomenon from the anion receptor by basic anion could be promising method for water sensing system.
