Abstract

The invention relates to a rhombic reticular coordination polymer based on NiII and a preparation method and application thereof. The adopted technical scheme comprises the following steps: respectively putting NiCl2.6H2O and organic aromatic diamine ligand into conical flasks, respectively adding absolute ethanol, and performing heating and stirring to enable the NiCl2.6H2O and the organic aromatic diamine ligand to be completely dissolved; then, pouring the NiCl2 solution into the organic ligand solution, adding a small amount of distilled water, and performing vibration and uniform mixing;and finally, performing sealing and perforation, standing the solution at room temperature for about 15 days to obtain green small granular crystals, and then, washing, filtering and drying the smallgranular crystals to obtain target products. Green blocky crystals suitable for an X-ray single-crystal diffraction experiment are obtained by diffusion of ethyl ether to the saturated ethanol solution of the small granular crystals. The rhombic reticular coordination polymer based on NiII, prepared by the preparation method provided by the invention, has fluorescent activity and can be used for detecting toxic solvent aromatic nitro compounds.

Description

technical field [0001] The present invention relates to a metal organic framework material, in particular to a Ni-based Ⅱ Rhombohedral network of coordination polymer materials. Background technique [0002] In the field of supramolecular chemistry, coordination polymers, also known as organometallic frameworks (MOFs), have been extensively studied as functionally diverse materials. Due to their large specific surface area, pores, and diverse topological structures, MOFs have been used in many fields, such as: nonlinear optics, superconductivity, catalysis, molecular recognition, biology, adsorption, etc. More importantly, the organic ligands in MOFs are variable, and its structure can be changed through certain group modifications, thereby changing its function. The properties and functions of rhombohedral network coordination polymers have attracted more and more attention from scientific researchers. In order to better apply rhombohedral network coordination polymer ma...
