摘　　要：以碱性品红为原料合成了一种黄色的三苯甲烷类染料FB-A,用IR、1HNMR表征其结构。研究了溶剂和pH对其吸收光谱和荧光光谱的影响,在酸性条件下,有蓝色荧光。在中性及碱性条件,荧光猝灭而且吸光度明显降低;随着溶剂极性增加,吸光度和荧光相对强度都减小。A kind of yellow triphenylmethane dye FB-A was prepared by FB. Their structures were established by IR,XH NMR. The absorption and emission spectra of dye as well as the influences of pH and solvent upon the spectra were investigated. In neutral or in basic media, the fluorescence was completely quenched and the absorption strength was obviously reduced. In strong polarity solvent, the absorption and emission contrast strength was reduced.

关 键 词：荧光光谱 PH效应 碱性品红
