芘是一种简单的芳香化合物,在溶液中可形成动态的和静态的激基缔合物,在长波长处出现荧光发射峰。利用单体和激基缔合物荧光波长的不同,芘常被用作荧光团来合成各种荧光化学传感器。本文对基于芘的荧光化学传感器的研究进展进行综述,主要包括其在单一阳离子、双阳离子和阴离子识别检测中的分子设计、作用机理和应用,并对该类荧光化学传感器的发展前景进行了展望。 Pyrene is a simple aromatic compound that can form dynamic and static excimer in solution and emits fluorescence emission at long wavelength. Pyrene is often used as a fluorophore to synthesize a variety of fluorescent chemosensors using the difference in the fluorescence wavelengths of monomers and excimer. This review summarizes the research progress of pyrene-based fluorescence chemosensors, including its molecular design, mechanism and application in the detection of single cation, double cation and anion, as well as the prospect of the development of such fluorescence chemosensors .
