Title
(EN) HIGH RESISTANCE POLYANILINE BLEND FOR USE IN HIGH EFFICIENCY PIXELLATED POLYMER ELECTROLUMINESCENT DEVICES
(FR) MELANGE DE POLYANILINE A HAUTE RESISTANCE DESTINE A ETRE UTILISE DANS DES DISPOSITIFS ELECTROLUMINESCENTS POLYMERES PIXELLES A HAUT RENDEMENT
Abstract
(EN)
Compositions are provided comprising polyaniline (PANI) with poly(2-acrylamido-2-methyl-1-propanesulfonic acid) (PAAMPSA) as the counterion (PANI/PAAMPSA) and an amount of poly(styrenesulfonic acid) (PSS) sufficient to reduce the conductivity of the composition relative to PANI/PAAMPSA. Invention compositions may further comprise poly(acrylamide) (PAM). Invention compositions are useful as high resistance buffer layers for use in electroluminescent devices (such as, organic light emitting diodes (OLEDs)).
(FR)
L'invention porte sur des compositions comprenant une polyaniline (PANI) avec un acide poly(2-acrylamido-2-méthyl-1-propanesulfonique) (PAAMPSA) comme contre ion (PANI/PAAMPSA) et une quantité d'un acide poly(styrènesulfonique) (PSS) suffisante pour réduire la conductivité de la composition par rapport à PANI/PAAMPSA. Les compositions de l'invention peuvent également comprendre un poly(acrylamide) (PAM) et sont utiles comme couches tampons à haute résistance dans des dispositifs électroluminescents (tels que des diodes organiques électroluminescentes (OLED).
