摘要

合成了一种新型Tröger基含芴酮有机聚合物(TB-FL-COP)，并将其用作水中抗生素的荧光传感器。TB-FL-COP对磺胺乙嘧啶类抗生素具有最高的荧光猝灭、可逆的传感响应和56 ppb水平的优异灵敏度。计算得到Stern-Volmer淬火常数(KSV)为1.2 × 106 M−1。荧光感应能力也通过明显的视觉颜色变化来体现，并在实际水样中得到进一步验证。

Tröger's base-containing fluorenone organic polymer for discriminative fluorescence sensing of sulfamethazine antibiotic at ppb level in the water medium†

A new Tröger's base containing fluorenone organic polymer (TB-FL-COP) was synthesized and used as a fluorescence sensor for discriminative sensing of antibiotics in water. TB-FL-COP showed the highest fluorescence quenching, reversible sensing responses, and excellent sensitivity of 56 ppb level for sulfamethazine antibiotics. The Stern–Volmer quenching constant (K_SV) was calculated to be 1.2 × 10⁶ M⁻¹. The fluorescence sensing ability was also reflected by sharp visual color changes and further demonstrated in real water samples.
