摘　　要：设计合成一种新型的罗丹明类荧光探针,通过核磁共振氢谱和电喷雾质谱(ESI)对其结构进行表征。通过可见吸收光谱和荧光光谱对其光学性能进行检测,包括:荧光滴定、荧光时间响应、离子干扰、pH响应等。结果表明:该探针可以专一性的识别锡离子,而不受其他金属离子的干扰;响应时间为5 min,线性检测范围为0~30μmol/L,检测限为1μmol/L。表明该探针是一种性能良好的荧光探针。A novel fluorescent probe is designed and synthesized. The structure is characterized by nuclear magnetic resonance hydrogen spectrum and electrospray mass spectrometry（ ESI）. The optical properties of the probe were investigated by UV-Vis and fluorescence spectrophotometry,including fluorescence titration,fluorescence time response,ion interference,pH response,etc. The results show that the probe can recognize the tin ions over other metal ions,with response time of 5 min. The linear range is 0-30 μmol/L and the detection limit is 1 μmol/L,which indicated that the probe is a fluorescent probe with excellent performance.
