Problems solved by technology

The introduction of molecular self-assembly technology into the preparation of electronic devices is attracting everyone's attention because it can obtain multifunctional films while maintaining the integrity of the film. Most of the molecular self-assembled films are established by electrostatic interaction. This has led to great limitations in the application of layer-by-layer assembly in the preparation of electronic devices, especially the formation of ordered self-assembled films on polymer substrates is difficult to achieve, mainly because the polymer substrate is homogeneous to the polymer film on it. , resulting in the interference of the self-assembly of the polymer film and the poor assembly effect
Therefore, in the prior art, the active layer of the electrical storage device is prepared in a way of miscibility between the polymer and the complex, which is convenient to operate but has many disadvantages. The obvious complex types are limited, and the content of the central metal atom is uncontrollable, resulting in the existing large Some memory devices are binary, and there are few types of active layer systems

Abstract

The invention discloses an active layer material and an application of the active layer material in preparing a ternary memory device. A thin film is prepared by synthesizing poly4-(4-methylacryloyloxy)-azo) pyridine with a solution spinning method; a metal complex layer is assembled on the surface of the polymer with a molecular self-assembly method; a polymer thin film is prepared with the solution spinning method, and an active layer is obtained. According to the device prepared from the active layer, stable multi-system storage is achieved; particularly, as the complex layer is introduced between the polymers with the molecular self-assembly method, transition of binary storage to ternary storage of the device is achieved.

Description

technical field [0001] The invention belongs to the technical field of storage devices; in particular, it relates to an active layer material and its application in preparing ternary storage devices. Background technique [0002] The concept of self-assembly technology was proposed in 1980. It refers to the technology of forming ordered molecular aggregates by adsorbing molecules containing active groups on the surface of a solid substrate. The formed molecular aggregates are also called molecular self-assembled films. In the 1990s, self-assembly technology was applied to surface chemistry, which promoted the research of self-assembly nanoparticle technology and broadened the research scope of self-assembly technology. The self-assembled monolayer film has a high degree of order and directionality, and the self-assembled film of organosilane derivatives can introduce functional groups in or at the end of the monolayer alkyl chain to change the wetting, corrosion, etching, et...
