Three 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 − , HSO 4 − and H 2 PO 4 − 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 1 H NMR titrations confirmed hydrogen binding interaction between the receptors and the anions.
