Research Abstract |
This study is a development of determination method for anions, such as phosphate or perchlorate, utilizing supramolecular complexation between fluorescent sensors based on photo-functional materials and a target anion. In the solution of triphenylamine derivative, fluorescence quenching at 460 nm was observed in fluorescence spectra with the addition of bis(diketonato)zinc(II) to form a ternary supramolecular complex. However, the addition of dihydrogenohosphate in the solution of the ternary supramolecular complex gave the enhancement of the emission intensity at 460 nm and 547 nm in fluorescence spectra. The calibration curve displays a good linear relationship between the emission intensity at 547 nm and the dihydrogenphosphate concentration (0-0.010 mM) with a detection limit of 3.4 nM.
