汞离子荧光探针的研究进展

Recent Progress in Mercury Ions Fluorescent Probes

汞是一种具有生物积累性的重金属元素,与一系列疾病的发生发展有密切联系。为了实现汞离子的实时原位可视化检测,近年来检测汞离子的有机小分子荧光探针发展迅速并有相关综述报道,但对于高分子荧光材料检测汞离子的研究报道极少。与其他汞离子研究进展综述不同之处在于以汞离子的检测机理为出发点,分别从设计原理、选择性、灵敏度和实用性角度出发,简要介绍了近年来有机小分子探针的设计策略,并详细介绍了基于功能高分子荧光材料检测汞离子的研究进展,将其检测策略归纳为配位型、反应型及两者结合型三类,以期为汞离子荧光探针的设计及发展提出新的研究思路。

Mercury is a heavy metal element closely related to the occurrence and development of a series of diseases on account of its bioaccumulation.In order to realize the in situ and real-time visual detection of mercury ions,small organic molecules based fluorescent probes for mercury ions have been developed rapidly in recent years and these related works have been summarized and reported as review papers,but the mercury ion probes fabricated using polymer fluorescent materials have been rare reviewed.The difference between this review and others was that the research progress of small organic molecule based mercury ions fluorescent probes was first briefly introduced and then highlights the advances in mercury ions detection using functional fluorescent polymer materials in recent years,including design principle,selectivity,sensitivity and practicality.The detection strategies were classified into three types,including coordination type,reaction-based type and combination type based on aspects of response mechanism strategy.This review would be helpful to design and develop ideal fluorescent probes for mercury ions detection.
