经由柔性连接臂化学单层组装于基质表面的多环芳烃,在基质表面有限区域内可以形成特定的超分子结构,并呈现相应的荧光光谱.这类结构及其光谱性质可因环境条件的变化而变化,基于这种变化可以设计制备传感薄膜材料.本文在概述此类研究工作的基础上,重点介绍了笔者实验室近年来,通过改变基质类型、调节连接臂长度和结构、优化多环芳烃的固定化密度等途径,设计制备对有关化学物质敏感且既可用于液相也可用于气相的荧光传感薄膜材料方面的研究工作.

Polycyclic aromatics chemically assembled on substrate surfaces via a flexible spacer in a monomolecular layer manner may form special supramolecular structures in a confined space, resulting in emission spectra of different characteristics. These structures and their spectra profiles are sensitive to changes in the conditions of their environment. On the basis of the principles described above, a number of novel sensing films, which can be used both in solution and in vapor phase, for various analytes have been designed and prepared. Following brief introduction of literature works in this field, relevant researches conducted in our laboratory are overviewed in detail.
