Embodiment 1

[0035] A method of preparing a nickel-based complex comprising the steps of:

[0036] A, use analysis of balance to accurately weigh 0.0050 g, 0.0133 mmol 2'-amino [1, 1 ': 3', 1 "- triphenyl] -4, 4", 5'-tricarboxylic acid (H 3 ATTCA) ligand and 0.0500 g, 0.138 mmol of hexahydrate nickel nickel in the reaction vessel, at room temperature, 2 ml of N, N-dimethylformamide and H were added to the reaction vessel. 2 O composition of mixed solvent, N, N-dimethylformamide with h 2 The volume ratio of O is 1: 1;

[0037] B. The solution in step A is placed in a glass bottle, and 36 h is stored in a constant temperature drum box at 100 ° C to obtain a green crystalline nickel-based complex.

[0038] The resulting green crystalline nickel-based complex

Abstract

The invention belongs to the technical field of new materials, and in particular relates to a nickel-based complex and its preparation method and application. The general chemical formula is {[Ni 1.5 (attca)(H 2 O) 3 ]} n , where n is an even number greater than 1, Ni is a divalent nickel ion, and attca is a deprotonated 2-amino[1,1:3,1-terphenyl]-4,4,5-tricarboxylic acid ligand ; Wherein, the nickel-based complex belongs to the orthorhombic crystal system, the Pmmb space group, and its unit cell parameters are axis major axis angle α=90°, β=90°, γ=90°, and the unit cell volume is Z=8 . The nickel-based complex of the present invention can be used to prepare adsorption materials, antibacterial materials, catalytic materials, photoelectromagnetic materials and drug carriers, belongs to a metal-organic framework structure, and is a composite functional porous material with great potential. Moreover, the nickel-based complex can be applied to the fields of fluorescence detection and gas adsorption separation.

Description

Technical field [0001] The present invention belongs to the technical field of new materials, and in particular to a nickel-based complex and a preparation method thereof. Background technique [0002] Metal-Organic Frameworks, Abbreviation MOFS is based on molecular identification and self-assembly, etc., with an organic ligand or organic bridge group with a special partition atom or a coordination functional group and a metal construction unit. A class of cyclic atrial materials having a cyclical network structure is obtained by self-assembly. Since MOFS generally has a large dimensional lattice inner hole, the outer surface orifice and the active position, the multi-change topology and the physical chemical properties, the object molecules enters the MOFS hole, which will act with the active site, so that MOFS is Gas adsorption and separation, drug targeted transportation and sustained release, fluorescent identification and catalytic and other fields have widely used. Also co...
