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 calix[4]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 calix[4]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.

Key words: calix[4]arene, fluorescence sensing film, chemical self-assembly, THF
