Description/Abstract
The intense yellow colour of the 4-nitrophenolate anion 2, in acetonitrile or dichloromethane solution, dissipates upon complex formation with meso-octamethylcalix[4]pyrrole 1.
The complex may be used as a colourimetric sensor for halide anions, such as fluoride, that displace the phenolate anion thereby restoring the yellow colour, characteristic of free 4-nitrophenolate anion, to solutions containing 1, 2, and the anion in question.
