The absorption and fluorescence spectroscopicresponses of three pyridiniumhemicyaninedyes to anions F−, Cl−, Br−, I−, H2PO4−, HSO4− and OAc− were investigated. At lower concentrations of OAc− (less than 1 equiv.), both the absorption and the fluorescence intensities of 1–3 were more effectively changed than F− at identical concentrations. At higher concentrations of OAc− (more than 1 equiv.), the
