Abstract

Polycondensation of perfluorobiphenyl with 1,4-dihydroxy- thioxanthen-9-one resulted in the title highly thermally stable polyether containing the thioxanthenone-type electron acceptor in-chain blocks in its structure. Model resistive memory devices based on it as the active medium exhibited a bipolar switching memristive effect with a 4-order difference in resistance between the low and high resistance states. The charge transport in this polyether is quantitatively described by the Nasyrov–Gritsenko model of phonon-assisted electron tunneling between traps.

八氟联苯-4,4'-二基 9-氧代硫杂蒽-1,4-二基聚醚--一种用于基于有机薄膜的忆阻器的有前途的材料：合成、忆阻效应和电荷传输机制

全氟联苯与 1,4-二羟基-硫杂蒽-9-酮的缩聚反应产生了标题所示的高热稳定性聚醚，其结构中含有硫杂蒽酮型电子受体链块。以这种聚醚为活性介质的模型电阻式存储器件显示出一种双极切换的忆阻效应，在低电阻状态和高电阻状态之间存在 4 阶电阻差。Nasyrov-Gritsenko 声子辅助电子阱间隧道模型定量描述了这种聚醚中的电荷传输。

期刊介绍： Mendeleev Communications is the journal of the Russian Academy of Sciences, launched jointly by the Academy of Sciences of the USSR and the Royal Society of Chemistry (United Kingdom) in 1991. Starting from 1st January 2007, Elsevier is the new publishing partner of Mendeleev Communications. Mendeleev Communications publishes short communications in chemistry. The journal primarily features papers from the Russian Federation and the other states of the former USSR. However, it also includes papers by authors from other parts of the world. Mendeleev Communications is not a translated journal, but instead is published directly in English. The International Editorial Board is composed of eminent scientists who provide advice on refereeing policy.
