Sulfonated polythiophenes comprising fused ring repeat units

摘要

A sulfonated polymer comprising a 3-substituted fused thienothiophene repeat unit, a composition comprising the polymer, a method of making the polymer, and a device comprising the polymer. The polymers can be used in hole injection or hole transport layers, or other applications in organic electronic devices.
