本发明属于化学分析检测技术领域,尤其涉及一种有机配合物汞离子探针及其制备方法与应用。
背景技术
汞离子在环境中的污染越来越危害到人类的健康,水体中的元素汞和无机汞可被微生物转化为甲基汞,并随着食物链上升而富集在动物和人体中。因此,处于食物链顶端的人类,是汞污染的最大受害者。大量吸入汞蒸汽会出现急性汞中毒,其症状为肝炎、肾炎、蛋白尿和尿毒症。无机汞主要对肾脏、肝脏损害。甲基汞可引起急慢性中枢神经系统损害及生殖发育毒性(Harris,H.H.;Pickering,I.J.;George,G.N.Science,2003,301,1203;Stefansson,E.S.;Heyes,A.;Rowe,C.L.Environ.Sci.Technol.2014,48,1957-1963)。
经典例子就是日本水俣病,表现为知觉障碍、运动失调、视力和听力障碍等。近年来,检测Hg2+的方法主要有紫外分光光度法、高效液相色谱法、原子吸收/发射光谱法等。这些方法能够很好的检测出Hg2+离子,但存在操作复杂、仪器昂贵、需要复杂的前期准备工作等缺点。因此,发展一种快速现场超灵敏检测水体系以及生物体中的Hg2+离子的方法已成为分析检测研究的一个重点,通过在荧光体系中引入磷光配合物基团,可以实现发光基团间的能量传递,降低探针自身的荧光背景,从而改善检测的信噪比,提高检测的准确性和灵敏性。

优选地,上述有机配合物汞离子探针在检测细胞中微量汞离子方面的应用。
本发明克服现有技术的不足,提供一种有机配合物汞离子探针及其制备方法与应用。在本发明中,有机配合物汞离子探针的合成过程,如图1所示。本发明利用罗丹明B分子具有高量子产率、良好的光稳定性、良好的水溶性等优点,结合了具有强拉电子基团的Ir(Ⅲ)的配合物,如图2所示,在没有汞离子存在的情况下,罗丹明B不开环,由于PET效应,会抑制Ir的发光;一旦汞离子与罗丹明B发生配位开环,PET效应阻断,会放出很强的罗丹明B的发射,这样就实现了一种低荧光背景干扰和高量子产率的汞离子探针。
相比于现有技术的缺点和不足,本发明具有以下有益效果:
(1)本发明利用罗丹明B对金属离子具有较好的选择性,实现对目标物汞离子的快速检测;
(2)本发明结合Ir配合物作为吸电子基团,降低了背景信号的干扰,提高了检测的灵敏度;
(3)本发明利用罗丹明B具有很高量子产率和荧光、磷光基团间的能量传递关系,放大检测信号,进一步提高检测的灵敏度;
(4)本发明适用于水相条件下应用,应用pH范围较宽;
(5)本发明设计的结构结合了荧光团和磷光团的各自特点,为探索新型结构的汞离子探针具有重要意义;
(6)本发明制备方法简单,发光稳定,操作便捷高效,适用于可以对溶液、泥土、生物细胞等中的汞离子实现定性、定量的快速检测,可以在环境检测,生物细胞成像等领域有广泛应用。
