AbstractTwo small molecular chromogenic sensors I and 2 for detection of Hg2+ are described. After coordination with Hg2+, a red shift of about 100 nm was observed in the UV/Vis spectra and the color of the solution changed from pale yellow to red which could easily be detected by the naked eye. The results indicate a strong push-pull system was formed after coordination of Hg2+. The H-1 NMR spectra and control experiments showed the binding sites of 1 and 2 to be the aniline groups rather than the azine bridge. Moreover, mercury test papers were made by adsorbing 1 onto filter paper, allowing heterogeneous sensing of Hg2+ in aqueous solution. ((C) Wiley-VCH Verlag GmbH & Co.
