Colorimetric sensing of fluoride ion by new expanded calix[4]pyrrole through anion-π interaction

Org Lett. 2012 Jan 20;14(2):548-51. doi: 10.1021/ol203165x. Epub 2011 Dec 29.

Abstract

Three new expanded calix[4]pyrroles were synthesized, where the two dialkylldipyrromethane units are linked via C-C double bonds. One of them, calix[2]bispyrrolylethene, colorimetrically senses fluoride ion only, owing to anion-π interaction in polar aprotic solvents.
