Abstract

Al(III) Electrochemical sensing Optical sensing Probe M1
A simple benzo[f]chromenone (M1) probe was synthesized and evaluated for its electrochemical and optical sensing response to Al(III) ions. Probe M1 exhibits a selective on-off colorimetric and off-on fluorescent sensing in the appearance of Al(III) ion. This probe also exhibits electrochemical sensing via DPV studies. The high sensitivity of M1 for Al(III) is exhibited with low detection limit 0.458 ppm. The resultant sensing is an outcome of CHEF and n-n interaction in rings.
