Abstract

The invention discloses a molybdenum-based supramolecular phase transition crystal material and a preparation method thereof. In the present invention, a solution 1 with a concentration of 0.2 to 0.4 mol / L is obtained by dissolving the "Mo=O-based" molybdenum metal compound in pure water, adding hydrochloric acid with a mass concentration of 36% to 38% into the solution 1 and letting it stand still, pumping Collect the filtrate after filtering the precipitate; wherein, the volume ratio of solution 1 to hydrochloric acid is (2-5): 10; 1,4-diazabicyclo[2.2.2]octane is dissolved in acetone to obtain a concentration of 0.05- 0.1mol / L solution 2, add the filtrate described in step (1) to the solution 2, mix uniformly, and let stand for 14 to 16 days to obtain a novel molybdenum-based supramolecular phase change crystal material; wherein, solution 2 and the filtrate The volume ratio is (5-8):10. The preparation process of the invention can be completed at room temperature, and compared with the synthesis process of the existing molybdenum-based supramolecular compound, the invention has better energy consumption and is safer.

Description

technical field [0001] The invention belongs to the field of new crystal materials, in particular to a molybdenum-based supramolecular phase transition crystal material and a preparation method thereof. Background technique [0002] Dielectric anomaly-phase change crystal materials have novel structures and excellent physical and chemical properties. They are indispensable intelligent materials for modern information storage, microelectronics, remote sensing, lasers, etc. Its special dipole arrangement structure and the characteristics of integrating light, electricity, magnetism, heat and force make it have a special application prospect that cannot be replaced by any material. [0003] Dielectric anomalies in the synthesis of metals and organics-phase-change crystal materials break the boundaries of inorganic-organic chemistry and promote the development of coordination compounds. Due to the diversity of metal ions and organic ligands, when using hydrogen bonds to construc...
