Embodiment 1

[0025] Example 1: Preparation of Europium-based Infinite Coordination Polymer Nanoparticles

[0026] 0.1mmol Eu(NO 3 ) 3 ·6H 2 O was dissolved in 5 mL of deionized water and stirred to obtain a clear and transparent solution. Add 20 mL of DMF solution dissolved with 0.1 mmol thienoyl trifluoroacetone (HTTA), put the mixed solution in a 40 mL polytetrafluoroethylene-lined stainless steel reaction kettle, and stir with a magnetic suspension stirrer for 10 min. Seal it and heat it in a 160°C electric blast drying oven for 6 hours. After the reaction was completed, it was naturally cooled to room temperature, and washed alternately with deionized water and absolute ethanol three times each. The obtained product was dried in a vacuum oven at 80° C. for 8 hours to obtain white europium-thiophenoyltrifluoroacetone infinite coordination polymer nanoparticles.

Embodiment 2

[0027] Example 2: Preparation of rare earth infinite coordination polymer film

[0028] 0.0298 g of the coordination polymer precursor prepared in Example 1 was dissolved in 2.6 mL of DMF solvent, and ultrasonically stirred, so that the sample was evenly dispersed in the DMF solvent. Add 0.4470g polymethyl methacrylate, put it in a stirrer and stir for 12h, set the low speed and high speed of the spin coater to 770r / min and 2220r / min respectively, and set the time to 15s and 20s respectively. Then, the obtained coordination polymer mixed sol was dropped on the sample sheet drop by drop to obtain a spin-coated film, which was air-dried to obtain a sample film at last.

[0029] The products prepared in Examples 1 and 2 were characterized respectively. The XRD pattern is tested and identified on an X-ray diffractometer (Bruker D8ADVANCE, Germany). The SEM image was taken on a scanning electron microscope (S-3400N, 30kV). The transmission electron microscope pictures were obtai...

Abstract

The invention provides a preparation method of europium-thenoyltrifluoroacetone infinite coordination polymer nanoparticles and a film thereof. The europium-thenoyltrifluoroacetone infinite coordination polymer nanoparticles are successfully prepared by taking Eu(NO3)3*6H2O as a metal ion source and thenoyltrifluoroacetone as an organic ligand and by a simple and template agent-free mixed solvothermal method; and the film is prepared by mixing the obtained dried sample and polymethyl methacrylate, taking N,N-dimethylformamide as a solvent and by using a spin-coating method. By adoption of themixed solvothermal method, energy is saved, operation is simple and convenient, and the shape and the granular size of the target product can be accurately controlled. The coordination polymer nano-sphere prepared by the method has uniform shape and has the diameter being about 100 nm, the prepared film has flat surface and high compact degree, and the synthesis route is simple and easy to regulate and control.

Description

technical field [0001] The invention relates to rare earth coordination polymers, in particular to a preparation method of europium-thienoyl trifluoroacetone infinite coordination polymer nanoparticles and a film thereof. Background technique [0002] Coordination polymers, as a new class of promising hybrid materials, have been extensively studied by researchers. Due to the variability of metal ions and organic ligands, as well as the variability of their building units, coordination polymers have unlimited structures and types and are used in a wide range of fields, including gas absorption, separation, catalysis, chemical sensing, Optoelectronic materials, green energy, bioimaging and drug delivery, etc. In the study of complex materials, it has become an important research direction for researchers to control the morphology and size of coordination polymer materials to control their properties and applications. Due to the unique characteristics of nanoparticles that ar...
