Embodiment 1

[0044] Add 0.31 g (1 mmol) TNbpdc to 15 mL of H 2 In O, adjust pH=6~7 with LiOH, dissolve the ligand, then add 0.291g (1mmol) Co(NO 3 ) 2 ·6H 2 O, stirred well, and placed in a stainless steel reaction kettle with a Teflon liner. at 5°C·min -1 The heating rate was programmed to 150°C, and kept for 48h, and then at 10°C·min -1 The rate program was cooled to room temperature, and there were purple-pink cubic crystal particles on the lining wall, filtered, washed, and dried in the air. The yield was 42% (by TNbpdc).

[0045] The complex is stable in air, insoluble in water and common organic reagents (including ethanol, ether and DMF).

[0046] The complexes prepared in Example 1 were characterized by infrared, differential scanning calorimetry and single crystal X-ray diffraction tests. The test parameters are as follows:

Abstract

The invention discloses an energetic type metal-organic framework material and a preparation method thereof. The complex consists of five metal ions Co(II), four 2,2'- binitro-4, 4'-biphenyldicarboxylic acid ligands, six coordinated water, two hydroxyls and sixteen crystal water. The preparation method for the energetic type metal-organic framework material comprises the following steps: adding the ligands into H2O, regulating the pH by use of LiOH, then, adding Co(NO3)2.6H2O, sufficiently stirring, placing into a stainless steel reaction kettle with a polytetrafluoroethylene lining; heating the stainless steel reaction kettle to 150 DEG C in a programmed manner and keeping the temperature for 48 hours, cooling the stainless steel reaction kettle to the room temperature in the programmed manner, leaving purple pink cubic crystal particles on the lining wall, filtering, washing and drying in the air to obtain the complex. The brisance and the work capability of the energetic material prepared by the preparation method are improved.

Description

technical field [0001] The invention relates to a material, in particular to an energetic metal-organic framework material and a preparation method thereof. Background technique [0002] Metal-organic frameworks, also known as porous coordination polymers, are self-assembled by metal ions or clusters and organic ligands to form a network skeleton structure, so they have a highly developed pore structure and a large relative area. Different types of metal elements and organic ligands and the diversity of coordination modes determine the different types and functions of metal-organic framework materials. [0003] Metal-organic coordination polymers (MOCP) are microporous polymers or zero-dimensional molecular cage materials with one-dimensional, two-dimensional or three-dimensional structures formed by self-assembly with metal ions as nodes and organic ligands as bridges. , this kind of microscopically highly ordered porous materials has aroused people's widespread interest b...
