| 摘要: 稀土发光传感器可用于有害的有机小分子胺的检测，然而稀土离子较大的离子半径和不稳定的配位构型，使其在固态下对有机小分子胺实现高灵敏性的发光检测具有一定的挑战。通过在单β-二酮配体上引入胺醇识别基团，使其与稀土铕离子通过配位成功构筑了具有可调控配体内电荷转移(ILCT)性质的单核稀土配合物[Eu (L)3(H2O)2](HL=(2Z)-1-(4-(双(2-羟基乙基)氨基)苯基)-4，4，4-三氟-3-羟基丁-2-烯-1-酮)。配合物的传感研究表明，[Eu (L)3(H2O)2]在弱的亲核作用下对三丙胺等有机小分子胺表现出明显的发光增强响应。 | |

| Abstract: As a kind of volatile toxic amines, organic small-molecule amines do great harm to human health. Therefore, the detection of organic small-molecule amines has attracted extensive attention. Lanthanide luminescence sensors stand out among all kinds of fluorescent sensors because of their easy synthesis, high biocompatibility, and high sensitivity. However, the large ion radius and unstable coordination configuration of lanthanide ions make it a challenge to achieve high-sensitivity luminescence detection of organic small-molecule amines in the solid state. The mononuclear lanthanide complex [Eu(L)3(H2O)2] (HL=(2Z)-1-(4-(bis(2-hydroxyethyl)amino)phenyl)-4,4,4-trifluoro-3-hydroxybut-2-en-1-one) with intraligand charge transfer (ILCT) properties was successfully constructed by the coordination of the mono-β-diketone ligand with the lanthanide ion europium by introducing the amine alcohol recognition group. The sensing study of the complex showed that [Eu(L)3(H2O)2] exhibited obvious luminescence enhancement response to small organic amines such as tripropylamine under weak nucleophilic action. | |
