Embodiment 1

[0035] A preparation method of a nickel-based complex, comprising the following steps:

[0036] A. Accurately weigh 0.0050g, 0.0133mmol of 2-amino[1,1:3,1-terphenyl]-4,4,5-tricarboxylic acid (H 3 attca) ligand and 0.0500g, 0.138mmol of nickel nitrate hexahydrate in the reaction vessel, at room temperature, add 2mL of N,N-dimethylformamide and H in the reaction vessel 2 A mixed solvent composed of O, N,N-dimethylformamide and H 2 The volume ratio of O is 1:1;

[0037] B. Put the solution in step A in a glass bottle and store it in a constant temperature blower box at 100°C for 36 hours to obtain a green crystal-like nickel-based complex.

[0038] The resulting green crystalline nickel-based complex

Abstract

The invention belongs to the technical field of new materials, and particularly relates to a nickel-based complex, and a preparation method and an application thereof. The chemical general formula of the complex is {[Ni1.5(attca)(H2O)3]}n, wherein 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. The nickel-based complex belongs to the orthorhombic system, has a Pmmb space group, and has the following cell parameters: the axial lengths comprise a being 3.4854(2) nm, b being 2.6440(2) nm and c being 0.63950(3) nm, the axial angles comprise alpha being 90 DEG, beta being 90 DEG and gamma being 90 DEG, the cell volume V being 5.8932(7) nm<3>, and Z is 8. The nickel-based complex of the invention can be used for preparing adsorbing materials, antibacterial materials, catalytic materials, photoelectromagnetic materials and drug carriers, belongs to a metal-organic framework structure, and is a highly promising composite functional porous material. The nickel-based complex can be applied to the fields of fluorescence detection and gas adsorption separation.

Description

technical field [0001] 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. Background technique [0002] Metal-organic frameworks (Metal-Organic Frameworks, referred to as MOFs) are based on molecular recognition and self-assembly behaviors, with organic ligands or organic bridging groups containing special coordination atoms or coordination functional groups and metal building units. A class of crystalline materials with periodic network structures obtained by self-assembly. Since MOFs generally have abundant lattice inner channels, outer surface pores and active sites, variable topological structures, and physical and chemical properties, after guest molecules enter the MOFs channels, they will interact with the active sites, so that MOFs It has a wide range of applications in the fields of gas adsorption and separation, targeted drug delivery and sustained release, ...
