Abstract

The invention discloses a metal terbium coordination polymer having fluorescent property and a preparation method of the metal terbium coordination polymer. The coordination polymer has a molecular formula of Tb4C72H7N24O24.5, has a one-dimensional chain structure, and is crystallized in a triclinic system, P-1 space group. The coordination polymer is prepared via a solvothermal method. The preparation method is simple and controllable and is beneficial for product crystallization, and the structure of prepared crystal is stable. The metal terbium coordination polymer can be taken as a fluorescent material, and can be widely applied to fields of military, industry, pharmacy and photoelectric materials.

Description

technical field [0001] The invention belongs to the technical field of fluorescent materials, and in particular relates to a metal terbium coordination polymer of a green fluorescent light-emitting material and a preparation method thereof. Background technique [0002] The preparation of metal-organic frameworks (MOFs) is increasingly favored by the academic community. These materials use the metal-ligand coordination between organic ligands and metal ions to self-assemble into supramolecular network structures. Its diverse structure has potential applications in gas storage, microelectronics, ion exchange, catalysis and other fields. Luminescent lanthanide complexes have been widely studied due to their extremely narrow emission bands, large Stokes shifts, long luminescence decay times, and theoretically no upper limit on quantum efficiency. Especially europium, terbium, samarium, and dysprosium have interesting luminescent properties, such as the red emission of Eu(III) ...
