Abstract

An organic molecule is disclosed comprising:a first chemical moiety with a structure of formula I,andtwo second chemical moieties, each at each occurrence independently from another consisting of a structure of formula II,wherein the first chemical moiety is linked to each of the two second chemical moieties via a single bond.

First claim

a first chemical moiety comprising a structure of Formula I,

and
two second chemical moieties, each independently from another comprising 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 is hydrogen;
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 is selected from the group consisting of hydrogen, and CF 3 ;
X is 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, and CF 3 ;
Y is the binding site of a single bond linking the first chemical moiety to one of the two second chemical moieties or is hydrogen;
