As the most emergent target for the construction of neuromorphic networks, the emulation of synaptic responses with a memristor on the device level has attracted much attention in both microelectronic industries and academic institutes. For this reason, a newly synthesized soluble push–pull type random conjugated polymer, that is, poly[{4,4′-(((9-H-fluorene-9,9-diyl)bis(4,1-phenylene))bis(oxy))diphthalonitrile}-(9,9-di-octylfluorene)-(macrocyclic triphenylamine)] (hereafter called PFFMT), was used to fabricate a memristor with a configuration of Al/PFFMT/ITO. The device shows interesting history-dependent memristive switching performance. The synaptic potentiation and depression, the transition from short-term plasticity to long-term plasticity, the relaxation time constant of the memory decay process, and the biological stimuli of the “learning–forgetting–relearning” processes associated to the human's learning/memory functions have been demonstrated. Upon being subjected to different voltages, the conductive nature of the as-prepared memristor has also been successfully revealed via the in situ conductive atomic force microscopy technique.

大环三苯胺基推挽型聚合物忆阻材料：合成与表征

作为构造神经形态网络的最紧急目标，在器件级别上使用忆阻器来模拟突触响应已在微电子行业和学术机构中引起了广泛关注。因此，新合成了可溶的推挽型无规共轭聚合物，即聚[{4,4'-（（（（9- H-芴-9,9-二基）双（4,1-亚苯基））双（氧基）二邻苯二甲腈}-（9,9-二辛基芴）-（大环三苯胺）]（以下称为PFFMT），用于制造具有Al / PFFMT构型的忆阻器/ ITO。该设备显示了有趣的历史依赖忆阻切换性能。突触增强和抑制，从短期可塑性到长期可塑性的转变，记忆衰退过程的松弛时间常数以及与人类的学习/记忆相关的“学习－忘记－再学习”过程的生物刺激功能已得到证明。在经受不同的电压，所制备的忆阻器的导电性质也已成功地发现通过在原位导电原子力显微镜技术。
