Abstract

A novel colorimetric chemosensor <bold>L</bold> has been developed for the detection of Ni<sup>2+</sup> and Cu<sup>2+</sup> ions. The obtained <bold>L</bold>–Cu<sup>2+</sup> complex can be used as a new cascade fluorescent-colorimetric sensor for the nanomolar detection of CN<sup>−</sup> ions. This chemosensor has practical application.
