摘要

重金属环境污染是现代生活中一个紧迫的当代问题。虽然铅污染具有历史性,但目前电池中铅的广泛使用可能会继续造成严重的环境问题。银离子也会带来多种环境问题,如生物蓄积性和毒性。因此,从环境和工业的角度来看,这两种重金属离子的影响很大。因此,对这两种金属离子的比色和荧光检测在过去十年中一直是研究的热点,而基于芘的荧光团在这两种金属离子的检测中起到了至关重要的作用。这篇综述文章按时间顺序总结了芘分子集成小分子化学传感器用于银离子和铅离子比色和荧光检测的最新进展。文章讨论了识别铅离子和银离子的不同策略。此外,还仔细研究了化学传感器的结构及其灵敏度,以及概述和未来展望。

Recent developments in pyrene-based fluorescence recognition and imaging of Ag+ and Pb2+ ions: Synthesis, applications and challenges

Contamination of heavy metals in the environment is a burning and contemporary issue of modern life. Whilst lead contamination is historic, the ongoing extensive use of lead in batteries is likely to continue to cause serious environmental problems. Silver ions also present multiple environmental issues, such as bioaccumulation and toxicity. As a result, these two heavy metal ions have a high impact from an environmental and industrial point of view. Thus, the colorimetric and fluorescence detection of these two metal ions has been the subject of intense research during the last decade and pyrene-based fluorophores have played a crucial role in their detection. This review article summarizes the recent chronological progress on pyrene moiety integrated small molecule chemosensors for the colorimetric and fluorescent detection of silver and lead ions. Herein, the different strategies that have been utilized for the recognition of lead and silver ions are discussed. Throughout, the juxtaposition of structural aspects of the chemosensors and their sensitivity has been scrutinized together with an overview and future vision.
