A novel multiple target sensor, (E)-5-((4-(diethylamino)-2-hydroxybenzyldene)amino)-1H-imidazole-4-carboxamide (DHIC), was synthesized for fluorescence detection of Zn²⁺ and S²⁻ and colorimetric detection of Fe^3+/2+ in aqueous media. DHIC can operate as a turn “on–off” sequential fluorescent sensor for Zn²⁺ and S²⁻. Detection limits (1.59 μM and 8.03 μM) for Zn²⁺ and S²⁻ are below the WHO standards (76.0 μM and 14.7 μM). The DHIC–Zn²⁺ complex could be reversibly reused with ethylenediaminetetraacetic acid. Importantly, DHIC could image sequentially Zn²⁺ and S²⁻ in living cells. Moreover, DHIC displayed a discriminatory color change from pale yellow to orange yellow to Fe^3+/2+. The detection limit of DHIC for Fe^3+/2+ (0.73 μM and 1.11 μM) is far below the EPA drinking water standard (5.37 μM). The sensor DHIC could be applied to analyze Fe³⁺ in real samples.

用于水介质和活细胞中Zn ²⁺和S ²⁻的顺序荧光检测以及Fe ^{3 + / 2 +}的比色检测的多目标化学传感器†

合成了一种新型的多目标传感器，（E）-5-（（4-（二乙基氨基）-2-羟基苄二烯）氨基）-1 H-咪唑-4-羧酰胺（DHIC），用于荧光检测Zn ²⁺和S ^2-和比色法检测水性介质中的Fe ^{3 + / 2 +}。DHIC可以用作Zn ²⁺和S ^2-的“开-关”顺序荧光传感器。Zn ²⁺和S ^2−的检出限（1.59μM和8.03μM）低于WHO标准（76.0μM和14.7μM）。该DHIC -Zn ²⁺该复合物可与乙二胺四乙酸可逆地重复使用。重要的是，DHIC可以对活细胞中的Zn ²⁺和S ^2-进行顺序成像。而且，DHIC显示出从浅黄色到橙黄色到Fe ^{3 + / 2 +}的可辨别的颜色变化。DHIC对Fe ^{3 + / 2 +}的检出限（0.73μM和1.11μM）远低于EPA饮用水标准（5.37μM）。DHIC传感器可用于分析实际样品中的Fe ³⁺。
