چکیده

Some colorimetric sensors containing the thiourea motif were synthesized and applied as naked-eye detectors in dimethyl sulfoxide/water solution. The ion detection studies displayed that the prepared compounds (1-4) act as selective, dual-sensitive chromogenic sensors to detect Cu2+, N3-, and I- ions. These chemosensors distinguish I- and N3- via naked-eye color changing from colorless to yellow, and red respectively in a paper test strips, besides a distinct red shift in UV-Vis. spectrum in nano scale. The result of Job's plot indicates that the stoichiometry binding ratios of compound 1 to corresponded ions are 1:1.
