Embodiment 1

[0039] Preparation of N,N-bis(4-aminophenyl)-1-aminoanthracene:

[0040] Under the protection of nitrogen atmosphere, add 1.9324g (10mmol) of 1-aminoanthracene, 3.2453g (23mmol) of p-nitrofluorobenzene, 3.45g of potassium carbonate, and 30ml of dimethyl sulfoxide into a 100ml three-necked flask, seal the system and turn on the magnetic force Stirring and heating, the temperature is set to 150°C. Stirring and heating were stopped after 48 hours of magnetic stirring. The solution in the three-necked flask was poured into ice methanol to obtain a bright yellow solid, and the obtained solid was washed with deionized water and ice methanol several times successively. After filtration, the solid was dried in a vacuum oven for 12 hours to obtain a bright yellow powder. Take 1.8774g of the bright yellow powder and put it into a 100ml three-necked bottle, then add 0.5315g of palladium carbon catalyst and 50ml of ethanol successively, turn on magnetic stirring and heating, set the temp...

Abstract

The invention provides soluble isomerized anthracene-containing polyimide with an information storage function, and belongs to the field of organic information storage materials. Isomerized anthracene-containing diamine with the electron supply property is firstly synthesized, and then isomerized anthracene-containing diamine and dicarboxylic anhydride with the electron acceptor property are subjected to polycondensation to prepare isomerized anthracene-containing polyimide with the excellent information storage function, wherein the structure of isomerized anthracene-containing polyimide is shown as a formula (I) (please see the formula in the description). Isomerized polyimide has the advantages of being low in switching voltage, high in response speed and stable in storage property, and the information storage behavior of the material can be regulated and controlled by changing the site where an anthracene group is connected into a polyimide main chain; in addition, polyimide has the good solubility in a polar solvent to be beneficial for material processing and preparing of an information storage device. Meanwhile, a preparation technology of polyimide is simple, high in efficiency and beneficial for batch preparation and has the very high practical value and the wide application prospect.

Description

technical field [0001] The invention belongs to the field of organic information storage materials, in particular to a soluble isomerized anthracene-containing polyimide with information storage function. Background technique [0002] As human beings enter the information age from the industrial age, the explosive growth of information makes electronic devices develop towards miniaturization and high density. The size of information storage elements gradually transitions from micron to nanoscale. Conventional semiconductor materials have reached the limits of their application in both the line width of devices and the size of memory spots. Therefore, the current problem that researchers must solve is how to develop new materials that can be used in the field of ultra-high-density information storage and how to prepare corresponding information storage devices. [0003] Among many materials, organic / polymer-based information storage materials have attracted extensive attent...
