Abstract
AbstractThree novel and simple N,N′‐diacylhydrazine‐based colorimetric receptors have been prepared. The binding properties of the receptors to anions such as F−, Cl−, Br−, AcO−, HSO4− and H2PO4− in acetonitrile solution were examined by UV‐Vis spectroscopy methods, which show high sensitivity and selectivity to F− and AcO− over other anions. The results indicated that a 1:1 stoichiometry complex was formed between the receptors and the anions, while 1H NMR titrations confirmed hydrogen binding interaction between the receptors and the anions.
