Problems solved by technology

However, the molecular design is limited by the type of monomer structure. In the research of this method, there are few effective and alternative electron donor units and electron acceptor units, which makes the selectivity of its structure and the improvement of its performance Adjustability is extremely limited
In the polyimide of the binary system, in order to achieve different information storage behaviors and better storage performance, it is necessary to replace the electron donor and acceptor units, or design a more complex electron donor and acceptor structure, and this Often have to go through complex and tedious chemical synthesis process
Contrary to expectations, this method of changing the type of donor acceptor and designing a new donor acceptor structure has a very limited effect on the regulation of material storage behavior and performance. In many cases, the redesign of the structure cannot bring about the improvement of material storage behavior. Tuning and optimization of storage performance, and sometimes weakening or even disappearance of storage behavior

Abstract

The invention belongs to the technical field of polymer information storage materials. By adopting a multielement copolycondensation process and using 4,4'-diamidotriphenylamine as an electron donor, 1,4,5,8-naphthyltetra formic anhydride as an electron acceptor and 9,9'-di(aminophenyl)fluorene as a third copolymerization unit, the composition of the copolymerization units is adjusted to successfully prepare the terpolymer polynaphthalimide with widely adjustable information storage behaviors. The structure is disclosed as Formula (I). The multielement copolycondensation process does not need special monomer design, can implement the functions of the material by using the existing monomer combination, and has the advantages of wide raw material sources and diversified structures. More importantly, the terpolymer polynaphthalimide has high performance adjustability, and can implement different information storage behaviors only by changing the copolymerization components, thereby effectively overcoming the defect that the binary system needs to synthesize a special monomer and has poor adjustability for the storage behaviors of the material. The process can be used for conveniently designing information materials with different storage behaviors according to needs, and thus, has very high practical value.

Description

[0001] Technical field: The present invention belongs to the technical field of polymer information storage materials, and specifically relates to a terpolymer polynaphthaleneimide with widely adjustable information storage behavior and its preparation. Background technique [0002] The 21st century is an era of knowledge economy with the information industry as the core. Various information technologies and information equipment have become an indispensable part of people's daily life. However, as human beings enter the era of "nanoelectronics" from the "microelectronics" era, traditional information storage materials, including magnetic storage, optical storage and semiconductor storage materials (such as silicon and germanium), no matter in the line width of the device or the storage point The size has gradually approached the upper limit of its application. Taking semiconductor storage as an example, the current integration level of a single computer chip has reached the ...
