AbstractA novel dicalix[4]pyrrolyl-substituted 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) dye I with an absorption peak at approximately 670 nm and an emission peak at about 690 nm was prepared. As an anion receptor, I displayed a red shift in absorption spectra and fluorescence quenching in varying degrees in the presence of F−, AcO−, H2PO4−, or Cl−. Compared with the parent calix[4]pyrrole, a representative anion receptor, I exhibited a stronger affinity to these anions due to the formation of a sandwich complex through multiple hydrogen-bonding interactions.

The neutral anion receptor 1 was synthesized by an easy method with high yield. The binding properties of anions with 1 were examined by UV-vis and 1H NMR spectroscopy. Receptor 1 can form a 1 : 2 complex with F−, and 1 : 1 complexes with AcO− and H2PO4− anions, respectively, by multiple hydrogen-bonding interactions. There is an observable colour change for the complex formed by 1 and F−.
