以二氰基二苯乙烯基苯衍生物（DCS-SE）为荧光探针，制备了一种新的荧光探针，用于盐酸小檗碱（BBC）的检测。通过光致发光光谱和扫描电子显微镜技术对DCS-SE的传感性能和机理进行了研究。实验结果表明，DCS-SE对水溶液中的BBC具有高选择性、快速响应和定量识别的特点。此外，由于静电相互作用诱导的聚集和随后的聚集诱导发射效应，DCS-SE表现出特殊的开启检测能力，检测限低至9.3 × 10− 8 M。本研究所提出的方法和原理可应用于设计和制备针对各种抗生素和生物分子的开启型荧光传感器。
A novel fluorescent probe based on water-soluble dicyanodistyrylbenzene derivative (DCS-SE) has been prepared for berberine chloride (BBC) detection. The sensing performance and mechanism of DCS-SE were elucidated by photoluminescence spectra and scanning electron microscopy techniques. The experimental results reveal that DCS-SE possesses high selectivity, fast response and quantitative recognition towards BBC in aqueous solution. Moreover, due to the electrostatic interactions induced aggregation and the subsequent aggregation-induced emission effect, DCS-SE exhibits special turn-on detecting ability, with detection limit as low as 9.3 × 10−8M. The strategy and principle outlined in this work may be applicable to design and prepare turn-on fluorescent sensors towards various antibiotic and biomolecules.
