CARBAZOLE-PYRIDINE-TRIFLUOROMETHYLPHENYL DERIVATIVES AND RELATED COMPOUNDS FOR USE AS TADF LUMINESCENT EMITTERS IN OLEDS

摘要

The invention relates to an organic compound, in particular for the application in organic optoelectronic devices. According to the invention, the organic compound has- a first chemical moiety with a structure of formula I,and- two second chemical moieties, both independently with a structure of formula II,wherein the first chemical moiety is linked to each of the two second chemical moieties via a single bond;whereinL^T is N or C-R¹; L^V is N or C-R¹; L^W is N or C-W; andexactly one ring atom selected from the group consisting of L^T, L^V and L^W is N,exactly one substituent selected from the group consisting of R^T, R^V and R^W is CF₃,exactly one substituent selected from the group consisting of W, Y and X represents the binding site of a single bond linking the first chemical moiety and one of the two second chemical moieties, andexactly one substituent selected from the group consisting of R^W, R^Y and R^X represents the binding site of a single bond linking the first chemical moiety and one of the two second chemical moieties.
