A new dual functional sensor: highly selective colorimetric chemosensor for Fe3+ and fluorescent sensor for Mg2+.

Abstract

A new artificial receptor 1 was synthesized for the detection of Fe(3+) and Mg(2+) in solution as a colorimetric and fluorescent sensor, respectively. The sensor exhibited highly selective and sensitive recognition towards Fe(3+) in CH(3)CN via color change from colorless to brown. Also it showed a significant fluorescence enhancement (70-fold) towards Mg(2… (More)
