Organic semiconducting polymers are promising electronic materials, but for full versatility they need to conduct negative as well as positive charge. A step towards that goal has now been taken.

Electronic devices based on organic materials are gradually becoming a mainstay of semiconductor technology, and are already used, for example, in flexible displays. However, a few hurdles remain before a breakthrough in practical applications can occur.
