AI Article Synopsis
- Researchers assessed the ability of polyaromatic organic layers to protect against reactive oxygen species (ROS) using advanced scanning electrochemical microscopy techniques.
- The layers were created by a process called electrografting with aryldiazonium salts, revealing that -(ethynyl)phenyl films were more effective at protecting surfaces compared to -(methyl)phenyl films.
- Managing the applied potentials and the electrolytes during the oxygen reduction reaction is crucial for minimizing ROS production and potentially extending the lifespan of electronic devices.
Article Abstract
The antioxidant protective properties of polyaromatic organic layers were evaluated toward reactive oxygen species (ROS) using scanning electrochemical microscopy in a foot-printing strategy. The layers were prepared by electrografting of aryldiazonium salts. Where -(methyl)phenyl films show only weak protective properties toward ROS, -(ethynyl)phenyl films evidence efficient protection of the covered surfaces. Applied potentials and electrolytes used during oxygen reduction reaction are critical parameters to control, prevent, or reduce the influence of ROS production and hence enhance the device lifetime.
