In the brain, both recording and decaying of memory information following external stimulus spikes are fundamental learning rules that determine human behaviors. The former is essential to acquire new knowledge update database, while latter filters noise autorefresh cache data reduce energy consumption. To execute these functions, brain relies on different neuromorphic transmitters possessing various kinetics, which can be classified as nonvolatile volatile memory. Inspired by electronic devices have been employed realize artificial neural networks spiking networks, respectively, emerged tools in machine learning. Molecular switches, capable responding electrical, optical, electrochemical, magnetic stimuli, display a disruptive potential for emulating storage devices. This Review highlights recent developments responsive molecules, their interfacing with low-dimensional nanostructures nanomaterials, integration into By capitalizing concepts, unique account neurotransmitter-transfer based molecules ad hoc kinetics provided. Finally, future directions, challenges, opportunities discussed use engineer more complex logic operations computing functions at hardware level.

The nanofiber microstructure is porous and can maintain the crystallinity of conjugated polymers during ion doping dedoping. However, there no report about applying self-assembled with a in organic electrochemical transistors (OECTs). Therefore, this study aimed to enhance OECT performance by fabricating thin films using self-assembly method poly(3-hexylthiophene) (P3HT) as active layer. also provide interface electrolytes facilitate penetration polymers. P3HT nanofibers are fabricated through mixed solvent system further refined ultrasonication UV irradiation. In situ electrochemical–optical analysis, ex grazing-incidence wide-angle X-ray scattering, atomic force microscopy utilized for structural analysis gain deeper insight into morphology their impact on device performance. An aqueous KPF6 electrolyte selected applied characterizations. This addressed instability issues associated hydrophilic like KCl. Among different configurations tested, undergoing without irradiation demonstrate excellent electrical properties stabile high hole mobility (μh) 0.385 cm2 s–1 V–1 figure-of-merits (μC*) 60.58 F cm–1 V–1, which significantly better than film counterpart μh 0.190 μC* 20.83 suggesting that well-ordered nanofibrillar structure effectively facilitates charge transport OECT. results new design approach tailoring fibrillar microstructures promote ion-doping capability applications.
