    摘要: The present invention relates to organic electroluminescent devices comprising a light-emitting layer B comprising two host materials, a n-type (electron-transporting) and a p-type (hole-transporting) host material, a thermally activated delayed fluorescence (TADF) material and an emitter material, which exhibits a narrow - expressed by a small full width at half maximum (FWHM) - deep-blue emission at an emission maximum of 440 to 475 nm. Further, the present invention relates to a method for generating blue light by means of an organic electroluminescent device according to the present invention.

    and
    - one second chemical moiety with a structure of formula II,

    wherein the first chemical moiety is linked to the second chemical moiety via a single bond;
    wherein
    T is the binding site of a single bond linking the first chemical moiety to one of the two second chemical moieties, or selected from the group consisting of R 1 and R T ;
    V is the binding site of a single bond linking the first chemical moiety to one of the two second chemical moieties or is hydrogen;
    W is the binding site of a single bond linking the first chemical moiety to one of the two second chemical moieties, or selected from the group consisting of R 1 and R T ;
    X and Y are selected from the group consisting of R 1 and R T ;
    wherein exactly one substituent selected from the group consisting of T, W, X, and Y is R T , and exactly one substituent selected from the group consisting of T, V and W represents the binding site of a single bond linking the first chemical moiety and the second chemical moiety; and
    wherein exactly one substituent selected from the group consisting of R I , R II and R III is L(R S ) 3 ,
    wherein L is selected from the group consisting of Si and Ge.

    摘要: The invention relates to an organic molecule, in particular for use in organic optoelectronic devices. According to the invention, the organic molecule consists of
    - a first chemical moiety with a structure of formula I,

    and
    - two second chemical moieties, each at each occurrence independently from another 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;
    wherein
    T, V is independently from another the binding site of a single bond linking the first chemical moiety to one of the two second chemical moieties or is hydrogen;
    W, X, Y is independently from another the binding site of a single bond linking the first chemical moiety to one of the two second chemical moieties or is selected from the group consisting of hydrogen, CN and CF 3 ;
    wherein exactly one substituent selected of the group consisting of W, X, and Y is CN or CF 3 , and exactly two substituents selected of the group consisting of T, V, W, X and Y represent the binding sites connecting of a single bond linking the first chemical moiety to one of the two second chemical moieties.
