AI Article Synopsis
- A redox-active molecule called 2,5,8-tri(4-pyridyl)1,3-diazaphenalene demonstrated unique non-volatile resistive switching memory due to its specific molecular orientation.
- The study revealed that the directional π-π interactions are crucial for creating conductive layers necessary for switching, differing from previous methods.
- These findings enhance our understanding of electron transport in organic materials, paving the way for a new type of resistive random access memory (ReRAM) using organic compounds.
Article Abstract
Control of the π-π interaction direction in a redox-active π-molecule based film led to the formation of new mechanistic nonvolatile resistive switching memory: a redox-active organic molecule, 2,5,8-tri(4-pyridyl)1,3-diazaphenalene, showed non-volatile bistable resistance states with a high on-off ratio, retention, and endurance only when the molecular orientation was anisotropic. Control experiments using redox-active/redox-inert organic molecules with isotropic/anisotropic molecular orientations implied that the formation of conductive oxidized π-π stacking layers from non-conductive neutral π-π stacking layers is responsible for resistive switching phenomena, indicating new mechanisms such as ReRAM. Our findings will give a comprehensive understanding of electron transport in organic solid materials based on the effects of redox-activity and molecular arrangement, leading to fabrication of a new class of ReRAM based on organic molecules.

Chemical reprogramming enables the generation of human pluripotent stem (hCiPS) cells from somatic cells using small molecules, providing a promising strategy for regenerative medicine. However, the current method is time consuming, and some cell lines from different donors are resistant to chemical induction, limiting the utility of this approach. Here, we developed a fast reprogramming system capable of generating hCiPS cells in as few as 10 days.
