挥发性有机化合物(Volatile Organic Compounds,VOCs)是重要的大气污染物,严重地危害着人类健康.本文设计合成了一种末端携带反应活性硅氧烷基团的杯[4]芳烃衍生物,通过自组装和表面化学反应将其共价结合于玻璃基质表面,获得了一种杯[4]芳烃修饰玻璃基质.以此基质物理担载荧光活性物质——芘封端三聚噻吩(Py-3T),得到了一种对气相四氢呋喃具有“turn-on”及快速灵敏(26.7 μg/mL)响应特性的荧光传感薄膜.实验表明:除苯和甲苯之外,其它常见有机溶剂和化学物质蒸汽对该薄膜荧光发射基本没有影响.苯和甲苯也因响应程度小、响应速度慢而难以干扰测定过程.据此,可以预期该荧光薄膜有可能在THF气体传感上获得应用.
