摘要：
Effect of the addition of six different anions on the absorption and fluorescence spectra of acridine yellow G (AYG) was examined. Only the F- anion could induce a visible color change observable with naked eye and a strong fluorescence quenching with K-SV of 8.3 x 10(4) mol(-1) L in CH3CN solutions. Calculated results of the interaction between the F-anion and acridine yellow G using the B3LYP/6-31G(d) program showed that the intermolecular charge transfer through the formation of an H-bond between AYG and F- is an essential sensor mechanism.
