N-2-pyridinylmethyl-N'-arylmethyl-diaminomaleonitriles: new highly selective chromogenic chemodosimeters for copper(II).
Copper chemodosimeters: The copper(II)-promoted air oxidation of 1-3 to form 4-6 permits the highly selective colorimetric detection of Cu(2+)  ions. The formation of copper(II) complexes of 4-6 proceeds rapidly, and the chemodosimeters 1-3 are viable at physiological pH.
