摘　　要：设计并制备了用于检测2,4,6-三氯苯酚的荧光分子印迹。由于铕配合物对模板分子的荧光淬灭作用,可用于荧光检测工具。荧光分子印迹在模板分子浓度范围0~70 nmol·L^(-1)内具有良好的荧光线性响应,相关系数为0.996 28。荧光分子印迹展现出了良好的灵敏度,其最低检出限为3.12 nmol·L^(-1)。荧光分子印迹具有较好的热稳定性,同时选择性检测实验证明荧光分子印迹对2,4,6-三氯苯酚具有良好的特异选择性。实验结果说明荧光分子印迹可用于选择性荧光检测低浓度氯酚类物质。Fluorescent molecularly imprinted polymers（FMIPs） for selective determination 2,4,6-trichlorophenol were devised and fabricated. Here, europium （Ⅲ） complexes were used as fluorescence detection tool via the fluorescence quenching with templates. The FMIPs have a linear fluorescent response in 0 ~70 nmol ·L^（-1） concentration range, and the correlation coefficient was 0.996 28. The FMIPs exhibit excellent sensitivity with the limit of detection of 3.12 nmol·L^（-1）. In addition, FMIPs show good thermal stability and appreciable selectivity over several analogues. The experimental results showed that FMIPs could be used for selective fluorescence detection of low concentrations of chlorophenols.
