Abstract

Functional polymers, such as semiconducting polymers and polyelectrolytes, play an essential role in polymeric devices due to their electronic properties. The performance of the devices depends on the properties of carriers within the molecules of functional polymers. Therefore, the carrier properties should be strongly influenced by the structures and physical properties of the films. In addition, an interfacial effect becomes more pronounced once the functional polymers are used in a thin-film state and integrated with other inorganic materials. How the chain packing and mobility affect the carrier properties in a thin film should be clarified to design more developed functional devises. In this focus review, the relationship among the aggregation states, the thermal molecular motion, and the carrier properties of the functional polymers and their interfacial effects are discussed.
