environment. To that end, a newly synthesized hybrid conjugated polymer with pendant carbazole rings, that is, poly(4-(6-(9H-carbazol-9-yl)hexyl)-4H-dithieno[3,2-b:2′,3′-d]pyrrole) (pC6DTP), was employed in the fabrication of a two-terminal memristor with a Al/pC6DTP/ITO configuration where the polymer was electrochemically doped. Signature biological synaptic responses to voltage spikes were demonstrated
作为最有可能构建神经形态网络的前景,用忆阻器模拟突触反应已经引起了微电子行业和学术界的关注。为此,新合成的带有咔唑侧环的杂化共轭聚合物,即聚(4-(6-(9 H -咔唑-9-基)己基)-4 H -二噻吩并[3,2- b :2] ',3'- d]吡咯) (pC6DTP) 用于制造具有 Al/pC6DTP/ITO 配置的两端忆阻器,其中聚合物被电化学掺杂。证明了对电压尖峰的标志性生物突触反应,例如增强和抑制以及尖峰时间依赖性可塑性。该器件能够通过 1 mV 脉冲进行编程,仅需要 100 fJ 的能量。据推测,聚合物的电压依赖性导电性质通过两种协同机制发生,一种与沿共轭聚合物主链的共轭有关,另一种与侧杂环相关。
