Abstract: A simple and novel receptor 1 based on indole-3-aldehyde and 2, 4-diphenylhydrazine is synthesized by a simple way, which displays good selectively and sensitivity for detection of acetate, fluoride and dihydregen phosphate anion in dry DMSO and in DMSO/H2O (95/5) solutions. Combining with the anions induces the visible color changes that the naked-eye detection maybe realized. Meanwhile, the binding properties are tested and determined by UV-vis, fluorescent changes and 1H NMR experiments in DMSO-d6.
