Functional ionic liquid and preparation method thereof

Abstract

The invention relates to a functional ionic liquid and a preparation method thereof. The structural formula of the ionic liquid is disclosed in the specification, wherein X<-> is Cl<-> (chloride ion), [BF4]<-> (tetrafluoroborate ion), [PF6]<-> (hexafluorophosphate ion) or [Tf2N]<-> (bistrifluoromethanesulfonimide ion), and n=0-15. After being introduced to the cation alkyl side chain of the ionicliquid, a phenanthroline group can coordinate with some metallic ions to form metallic coordination compounds, and can absorb energy and transfer the absorbed energy to the metallic ions so as to coordinate with rare earth ions, thereby being used for preparing a rare earth compound / ionic liquid material. The prepared material has the advantages of colorful emitted light, high color purity, long fluorescence lifetime and high quantum efficiency, and is applicable to the fields of display, new light sources, X-ray intensifying screens and the like.

Description

Technical field:

[0001] The invention belongs to the field of ionic liquids, and relates to heterocyclic compounds that can be used as ionic liquids, in particular to a functionalized ionic liquid and a preparation method thereof. Background technique

[0002] Ionic liquids generally consist of salts of organic cations. Organic cations are generally bulky and asymmetric, such as: N-methyl-N-alkylpyridinium, N-alkylpyridinium, 1-alkyl-3-alkylimidazolium and tetraalkylammonium ions. Ionic liquids are considered to be the most promising solvents in green chemistry and cleaning processes because of their non-volatility, wide liquid range, high electrical conductivity, high thermal stability, and adjustable properties.

[0003] There are many kinds of ionic liquids, but most of the functionalized ionic liquids currently synthesized do not contain lone pairs of electrons and are not easy to coordinate with metal ions.

[0004] O-phenanthroline has a good planar structure and a s...
