Title (EN) ASYMMETRIC MESOGENS AND A METHOD OF MANUFACTURE
(FR) MÉSOGÈNES ASYMÉTRIQUES ET LEUR PROCÉDÉ DE FABRICATION
Abstract:
(EN) The invention relates to an asymmetric mesogen for use in an OLED device, wherein the asymmetric mesogen has the structure (I): E1-(B1)n-A-B2-E2 wherein: (B1)n-A-B2 is a chromophore that comprises a conjugated pi-system, wherein A, B1 and B2 each independently comprise an optionally substituted aromatic ring system; E1 and E2 are end groups which terminate the conjugated pi-system of the chromophore; n is 0 or 1; and wherein the asymmetric mesogen does not possess a C2 symmetry axis.
(FR) L'invention concerne un mésogène asymétrique destiné à être utilisé dans un dispositif OLED, le mésogène asymétrique ayant la structure (I) : E1-(B1)n-A-B2-E2 dans laquelle : (B1)n-A-B2 est un chromophore qui comprend un système pi conjugué, dans laquelle A, B1 et B2 comprennent chacun indépendamment un système cyclique aromatique éventuellement substitué ; E1 et E2 sont des groupes terminaux qui terminent le système pi conjugué du chromophore ; n est égal à 0 ou 1 ; et le mésogène asymétrique ne possédant pas d'axe de symétrie C2.
