Novel luminescent vesicles with enhanced emission were achieved by an amphiphilic Eu complex through its spontaneously self-assembly in an ionic liquid, 1-butyl-3-methylimidazolium hexafluorophosphate ([Bmim]PF6). The complex was prepared by Eu ions coordinated with terpyridine ligands, which were modified with the hydrophilic ethoxy chains. The enhanced absolute quantum yield and prolonged fluorescence lifetime of complex in vesicles were observed because of the effective shielding of the quench effects caused by both solvent and complex concentration Compared to the aggregates formed in other solvents, the vesicles obtained in [Bmim]PF6 showed the best luminescence intensity with the quantum efficiency (37.74%) and luminescent emission lifetime (1.915 ms) both increased ∼10 times more. This Eu complex was designed to show unsaturated coordination, which made the vesicle luminescence easily quenched when contacting with H2O. The fluorescence sensing of H2O with this vesicle as probe was possible, where several unique properties like high sensitivity, low detection limit (0.05 volume%), visible color change, and fast response had been observed Such designed systems are expected to provide strategies to develop novel supramol. aggregates in ionic liquids and offer guidance for luminescence detection with facile and wide applications. In the experiment, the researchers used many compounds, for example, 2-(2-Methoxyethoxy)ethanol (cas: 111-77-3Related Products of 111-77-3).
2-(2-Methoxyethoxy)ethanol (cas: 111-77-3) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. At room temperature, ethers are pleasant-smelling colourless liquids. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive, and as a result they are useful as solvents for fats, oils, waxes, perfumes, resins, dyes, gums, and hydrocarbons. Vapours of certain ethers are used as insecticides, miticides, and fumigants for soil.Related Products of 111-77-3
