Conducting polymer systems for hole injection or transport layer applications including a composition comprising: a water soluble or water dispersible regioregular polythiophene comprising (i) at least one organic substituent, and (ii) at least one sulfonate substituent comprising sulfonate sulfur bonding 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.

La présente invention concerne des systèmes polymères conducteurs pour des applications d'injection de trous ou de couche de transport comprenant une composition comprenant : un polythiophène régiorégulier soluble dans l'eau ou dispersible dans l'eau comprenant (i) au moins un substituant organique et (ii) au moins un substituant sulfonate comprenant du sulfure de sulfonate se liant directement au squelette du polythiophène. Le polythiophène peut être soluble dans l'eau, dispersible dans l'eau ou peut gonfler dans l'eau. Il peut être autodopé. Le substituant organique peut être un substituant alcoxy ou un substituant alkyle. Des applications OLED, PLED, SMOLED, PV et ESD peuvent être utilisées.
