A new artificial receptor 1 was developed, and its chromogenic and fluorogemc behaviors toward various metal ions were investigated. Receptor 1 shows exclusively responses toward Hg2+ and Cu2+. ions It selectively senses Hg2+ and Cu2+ ions through two different color changes in aqueous solution (DMSO/H2O=4/1) and also distinguishes them from other metal ions In addition, receptor 1 also exhibits pronounced enhancements of the fluorescence, which can visually be discernible by an orchid fluorescence in the presence of Hg2+ ions and a strong blue fluorescence in the presence of Cu2+ ions.
