文摘

A novel colorimetric chemosensor 1 for sequential detection of Ni2+ and CN− was developed. Detection limit of 1 for Ni2+ was down to nanomolar concentration (57 nM). Sensing ability of 1 for Ni2+ was successfully carried out in real water samples and visible test strips. The resulting 1-Ni2+ complex acted as an efficient colorimetric chemosensor for CN−.
