MEASURING TWO POLARONS IN A POLYMER

摘要

Plastics or polymers are normally considered to be nonconducting, but conjugated or conducting polymers can carry current just like metal wires and can be used in devices such as solar cells and light emitting diodes. John R. Miller, Lori Zaikowski, and co-workers did experiments and calculations to describe how charge travels along conducting polymers (DOL 10.1021/ja301494n).rnCharges called polarons move through conducting polymers by hopping along and between polymer chains. To fully understand this movement, it is important to know if multiple charges exist as separate polarons on the same chain.
