Embodiment 1

[0023] 5mmolZnCl 2 Mixed with 5mmol2-methylimidazole in 50mL of water, at room temperature, a kind of coordination compound (2MI)[Zn(2MI)Cl with reversible dielectric properties was obtained by self-assembly by solution method and slow evaporation of solvent. 3 ]

[0024] The coordination compound crystals obtained in Example 1 were characterized. Select a single crystal of appropriate size under a microscope, and use graphite monochromatized MoKα rays at room temperature The X-ray diffraction structure of the single crystal was determined on a Bruker ApexIICCD diffractometer, and the results are shown in Table 1. The SADABS method was used for semi-empirical absorption correction, the unit cell parameters were determined by the least squares method, data reduction and structure analysis were completed using the SAINT and SHELXL program packages, and all non-hydrogen atoms were anisotropically refined by the full matrix least squares method. The minimum asymmetric unit dia...

Description

technical field [0001] The invention belongs to the technical field of synthesis of reversible dielectric materials, and specifically relates to a metal-organic coordination compound with reversible dielectric properties, a preparation method and an application. Background technique [0002] Dielectric materials can be used to control / storage charge and electrical energy, and have an important strategic position in modern electronic and power systems. People's research on dielectric materials started from inorganic piezoelectric ceramic materials. Inorganic piezoelectric ceramic materials have high dielectric constant and high thermoelectric stability, but they are brittle and have high processing temperature. With the rapid development of the information and microelectronics industry, the application requirements for miniaturization, integration, intelligence, high frequency and planarization of semiconductor devices have increased. More and more electronic components, such...
