Embodiment 1

[0021] Embodiment 1. Weigh 0.1mmol H 3 L with 0.15mmolTb(NO 3 ) 3 ·6H 2 O was added to a 15ml polytetrafluoroethylene tube, and 5ml DMF was added, and stirred at room temperature for 30 minutes. The polytetrafluoroethylene tube was sealed in a stainless steel reaction kettle, the temperature was controlled at 120°C and heated for 72 hours, and the temperature was naturally lowered. Colorless blocky crystals were precipitated overnight, washed and dried in vacuum. The yield of the obtained terbium complex was 84%.

[0022] Structure determination of terbium organic framework complexes:

[0023] Select a single crystal with a suitable size under a microscope, and use X-ray diffraction to monochromatize Mo-Kα rays through a graphite monochromator with a Bruker Smart Apex II detector, scan mode ω, and collect data at a temperature of 293K. All diffraction data were subjected to semi-empirical absorption correction using the SADABS program after SAINT reduction. The crystal st...

Embodiment 2

[0029] Embodiment 2. Weigh 0.1mmol H 3 L with 0.15mmolTb(NO 3 ) 3 Add to a 15ml Teflon tube and add 5ml H 2 O, stirred at room temperature for 30 minutes. The polytetrafluoroethylene tube was sealed in a stainless steel reaction kettle, and after heating at 120°C for 72 hours, the temperature was naturally lowered, and no crystals were precipitated overnight, and a large amount of white powder was obtained.

Embodiment 3

[0030] Embodiment 3. Weigh 0.1mmol H 3 L with 0.15mmolTb(NO 3 ) 3 Add to a 15ml polytetrafluoroethylene tube, and add 5ml of H at a volume ratio of 1:1 2A mixed solvent of O and DMF was stirred at room temperature for 30 minutes. Seal the polytetrafluoroethylene tube in a stainless steel reaction kettle, heat it at 120°C for 72 hours, cool down naturally, and precipitate colorless blocky crystals overnight, wash them, and dry them in vacuum. was 43%.

Abstract

The invention discloses a terbium organic framework complex and a preparation method thereof. A chemical formula of the terbium organic framework complex is [Tb(L)(DMF)2]n, wherein H3L is 5-(4'-formyl phenoxy)methyl meta-phthalic acid, DMF is N,N'-dimethylformamide. The terbium organic framework complex can be prepared through a solvothermal method which comprises the following steps: adding an H3L ligand and Tb(NO3)3.6H2O of which a mass ratio is 1 to 1.5 into the DMF in a certain volume, stirring for 30 minutes at a room temperature, and keeping the temperature in a sealed reaction kettle be 120 DEG C and reacting for 72 hours; cooling at the room temperature, obtaining colorless blocky crystals, washing, and vacuum drying, wherein the yield is 84 percent. When the terbium organic framework complex disclosed by the invention is excited by using light of which the wavelength is 380 nm, stronger characteristic green light can be emitted, CIE (Commission Internationale de I'Eclairage)) chromaticity coordinates are (0.2886, 0.5094), the fluorescent lifetime is 3.328 ns, and the quantum yield is up to 81.8 percent, so that the terbium organic framework complex can be used as a potential optical material.

Description

technical field [0001] The present invention relates to rare earth metal complexes, in particular to a terbium organic framework complex, in particular to a terbium (III) ion and 5-(4'-formic acid phenoxy)methyl isophthalic acid structure with luminescent properties Terbium complex and its preparation method. Background technique [0002] Rare earth metal complexes have broad application prospects in the fields of luminescence, catalysis, and biomedicine due to their optical, electrical, and magnetic properties. Among them, rare earth metal organic complexes as photoluminescent materials are compared with traditional inorganic luminescent materials. , due to the unique structure and properties of rare earth ions, they have the advantages of high luminous intensity, pure fluorescent color, low excitation energy, high fluorescent efficiency, and easy solubility in organic media after they are coordinated with organic ligands. Therefore, it is considered to be the most promisi...
