SULFONATION OF CONDUCTING POLYMERS AND OLED, PHOTOVOLTAIC, AND ESD DEVICES

摘要

Conducting polymer systems for hole injection or transport layer applicat ions including a composition comprising: a water soluble or water dispersibl e regioregular polythiophene comprising (i) at least one organic substituent , and (ii) at least one sulfonate substituent comprising sulfonate sulfur bo nding directly to the polythiophene backbone. The polythiophene can be water soluble, water dispersible, or water swellable. They can be self-doped. The organic substituent can be an alkoxy substituent, or an alkyl substituent. OLED, PLED, SMOLED, PV, and ESD applications can be used.
