Abstract
Copolymers of 3,4-dialkoxythiophenes are disclosed that are useful as electronics materials. Also disclosed are methods of making these copolymers, as well as compositions and devices incorporating them. Use of these materials in hole injection or hole transport layers is disclosed. Materials comprising these copolymers can be designed to provide solubility in some solvents and intractability in others, which is useful for the construction of multilayer materials for use in electronic devices.
