多年来,我们开发了针对水中K + 的高选择性荧光探针,其显示出 K +诱导的荧光强度增强、寿命变化或在两个发射波长下的比率行为(参见方案 1,K1 – K4)。在本文中,我们介绍了水中Na +的选择性荧光探针,也显示了 Na +诱导的信号变化,并通过不同的荧光技术进行了分析。最初,我们合成了荧光探针2、4、5、6和10,通过改变 Na +响应离子载体单元和荧光团部分来调整细胞内或细胞外的不同K d值,通过在一个波长下强度增强进行荧光分析。 Na +分析。因此,我们发现2、4和5是Na +选择性荧光工具,它们能够在高于500 nm的波长下测量生理上重要的Na +水平。其次,我们开发了荧光探针7和8,通过荧光寿命的变化来分析精确的Na +水平。在此,只有8 ( K d = 106 m m ) 是一种能够通过寿命变化测量血液样本中Na +水平的荧光工具。最后,荧光探针9被设计为在两个发射波长处显示Na

The present invention relates to π-conjugated fluoroionophores, methods for their preparation, and their use and a method for determining an alkali ion. Fluoroionophoric compounds of the general formula I are described Ionophore – π-Linker - Fluorophore (I) wherein the Ionophore is an anilino containing crown ether or cryptand with one or more anilino donor moieties as electron donors, forming a stable complex with an alkali metal ion the π-Linker is an aromatic or heteroaromatic conjugative linking moiety, and the Fluorophore is an electron acceptor moiety. Variation of the ionophoric unit offers a broad spectrum of detectable K+ and Na+ -concentrations, ranging from high concentration around 800 mM down to very low concentrations around 3 mM. The fluoroionophores have great potential for application in fluorescent optode system based blood analyzing equipment for methods and kits for the determination of K+ and Na+ concentrations in biological systems, either in vitro or in vivo, using embodiments of the disclosed fluoroionophores.

is a tremendous demand for highlyNa+-selective fluoroionophores to monitor the top analyte Na+ in life science. Here, we report a systematic route to develop highlyNa+/K+ selectivefluorescentprobes. Thus, we synthesized a set of fluoroionophores 1, 3, 4, 5, 8 and 9 (see Scheme ) to investigate the Na+/K+ selectivity and Na+- complex stability in CH3CN and H2O. These Na+-probes bear different 15-crown-5
developed the fluorescent probes 7 and 8 to analyze precise Na+ levels by fluorescencelifetimechanges. Herein, only 8 (Kd=106 mm) is a capable fluorescenttool to measure Na+ levels in blood samples by lifetimechanges. Finally, the fluorescent probe 9 was designed to show a Na+ induced ratiometricfluorescence behavior at two emission wavelengths. As desired, 9 (Kd=78 mm) showed a ratiometric fluorescence
