The absorption and fluorescence spectroscopic responses of three pyridinium hemicyanine dyes 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
三个吡啶鎓半花青染料阴离子的吸收和荧光光谱响应˚F - ,氯- ,溴- ,我-,H 2 PO 4 -,HSO 4 -和OAC -进行了研究。在较低浓度的OAC - (小于1当量),在吸收和荧光强度二者1 - 3分别除F更有效地改变-在相同的浓度。在较高浓度的OAC - (多于1当量),该相互作用是每种化合物相反。1个1 H NMR结果表明的相互作用之间1,2或3和F -通过氢键进行。结果表明,这些染料是有希望开发双荧光朝˚F显色化学传感器-和OAC -根据F的亲和力的细微差别-和OAC - 。
