Transparent electrode for optoelectronic devices

摘要

Transparent electrode comprises first layer of conductive polymer on which is applied a second layer containing a polymeric anion and at least one optionally substituted polyaniline and/or polythiophene. Transparent electrode comprises first layer of conductive polymer on which is applied a second layer containing a polymeric anion and at least one optionally substituted polyaniline and/or polythiophene. The polythiophene comprises repeating units of formula (I): [Image] A : optionally substituted 1-5C alkylene; R : OH or optionally branched and/or substituted 1-18C alkyl, 5-12C cycloalkyl, 6-14C aryl, 7-18C aralkyl or 1-4C hydroxyalkyl; x : 0-8. Independent claims are included for: (1) method for preparing the transparent electrode; and (2) electroluminescent device comprising at least two electrodes, at least one being an (A), and an electro-optically active layer between the electrodes.
