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 aromatic hydrocarbons (PAHs) assembled on the surface of the matrix through a flexible linker can form specific supramolecular structures in the limited area of the substrate surface and exhibit corresponding fluorescence spectra. Such structures and their spectral properties can vary with changes in environmental conditions, and based on this change, thin film materials can be designed and fabricated. In this paper, based on the overview of such research work, this paper mainly introduces the author’s laboratory in recent years, by changing the matrix type, adjusting the length and structure of the connecting arm, optimizing the PAH density and other ways to design and preparation of the chemical sensitive And can be used for both liquid and gas-phase fluorescence sensing thin film materials research work.
