  • The instability of n-type organic semiconductors in air is a long-standing challenge in organic electronics. Now, a strategy based on the use of vitamin C is developed to stabilize organic semiconductors. Vitamin C scavenges reactive oxygen species and inhibits their generation, improving the performance and stability of organic semiconductors and their electronic devices.
