compounds was investigated in THF. Among the different anions, significant changes in the fluorescence spectra of HPB-1 and HPB-2 were observed in the presence of only F− ions. The interaction ratios of HPB-1 and HPB-2 with F− ions were determined to be 1 : 1 and the binding constants (KA) were found to be 0.0417 M−1 and 0.982 M−1 for HPB-1 and HPB-2, respectively. The LOD values were calculated as
