Abstract

The invention discloses a chiral blue-light emitting material 3D (three-dimensional) indium-potassium dissimilar-metal organic framework and a template synthetic method and application thereof. The invention relates to a 3D indium-potassium dissimilar-metal organic framework and a template synthetic method and application thereof. The chiral blue-light emitting material 3D indium-potassium dissimilar-metal organic framework and the template synthetic method and the application thereof aim at solving the technical problems that a high-dimension novel structure is quite difficultly synthesized by using an existing blue-fluorescence organic light-emitting material, the synthetic cost is high, and the productivity of products is low. The molecular formula of the chiral blue-light emitting material 3D indium-potassium dissimilar-metal organic framework is [InK2C20H14Cl3N2O5]n. The template synthetic method comprises the following steps of putting achiral 2, 3-quinoline dioctyl phthalate, potassium hydroxide and indium chloride into distilled water, agitating an obtained mixture at a room temperature until the obtained mixture is mixed uniformly, and then putting mixed liquor into a stainless steel reaction kettle of which the liner is made of polytetrafluoroethylene, carrying out reaction at a certain temperature, and finally cooling to the room temperature. The application is that the chiral blue-light emitting material 3D indium-potassium dissimilar-metal organic framework is used as a metal organic blue light-emitting material.

Description

technical field [0001] The invention relates to a 3D indium-potassium heterometallic organic framework and a template synthesis method and application thereof. Background technique [0002] Chiral solid materials have attracted more and more attention because of their great potential applications in enantioselective separation, heterogeneous asymmetric synthesis, nonlinear optics and magnetism. In recent years, relatively mature metal-organic framework materials or coordination polymers containing inorganic and organic units have shown their potential in the preparation of chiral materials. The usual way to prepare chiral compounds is to use a chiral molecule as a basic linking unit or as an auxiliary ligand, which is the most effective way to synthesize chiral compounds. However, the synthesis of chiral compounds from achiral precursors has been highly favored due to the limitation of chiral sources and the cost of chiral ligands. On the other hand, since 8-hydroxyquinoli...
