摘要
设计合成了含有酚羟基的氟硼荧类荧光探针分子1,利用紫外–可见吸收光谱和荧光发射光谱研究了探针分子1的阴离子识别和光化学传感性能。研究结果表明,该探针分子可以通过紫外–可见吸收光谱和荧光发射光谱双通道识别检测氟离子。该探针分子是一类“开–关”型阴离子荧光探针,作用方式为探针分子酚羟基与阴离子之间的氢键作用。通过本实验不但可以让学生掌握紫外–可见吸收光谱和荧光发射光谱仪的使用方法,还能培养学生在分子识别与光化学传感领域的科研兴趣,为进一步的科研工作打下基础。
A BODIPY-based fluorescent sensor 1 has been developed and their recognition and sensing abili-ties with various anions have been studied in solution by absorption and emission spectroscopy. Sensor 1 showed selective response toward fluoride anions through hydrogen bonding interaction with ON-OFF fluorescent behaviors. Through this experiment, it allows students not only mastering how to operate the UV-visible absorption and fluorescence emission spectrophotometers, but also cultivating the research interest in the field of molecular recognition and photochemical sensing.
