摘    要: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.

关 键 词:杯[4]芳烃  荧光传感薄膜  化学自组装  四氢呋喃

Abstract:Volatile organic compounds (VOCs) are major components of atmospheric pollutants which are harmful to human being. In this work, a novel di-urea bridged calix4]arene derivative ended with siloxane was designed and synthesized. The compound was then utilized for the modification of pre-cleaned glass plate surface, and in this way, a substrate with a layer of calix4]arene was fabricated. Upon dip-coating a fluorescent compound, pyrenyl derivative of terthiophene (Py-3T), onto the substrate surface, a fluorescence "turn-on" film sensor for THF in vapor phase was developed. It was demonstrated that the film is highly sensitive to the presence of THF vapor (DL, 26.7 μg/mL), and the sensing is fast and reversible. With exception of benzene and toluene, other commonly found organic liquids and chemicals show little effect upon the sensing. It is believed that the film may have real-life uses in THF sensing.
Keywords:calix[4]arene  fluorescence sensing film  chemical self-assembly  THF
