A Cu(<scp>ii</scp>)-based chemosensing ensemble bearing rhodamine B fluorophore for fluorescence turn-on detection of cyanide

Abstract

A Cu(II)-based 2 : 2 chemosensing ensemble bearing rhodamine B fluorophore was developed for fluorescence turn-on detection of CN− with high selectivity and sensitivity based on the CN− complexation to the Cu2+ centre in the nearly planar central binding moiety.
