Claim 0:
1. An organic molecule comprising:
a first chemical unit comprising a structure of the Formula A1:, one second chemical unit comprising a structure of the Formula D1:, with
#=point of attachment of the second chemical unit to the first chemical unit;
RN comprises a structure of the Formula N1:, with
§ =point of attachment of the chemical unit of Formula N1 to the first chemical unit;
RN2 is the same or different at each instance and is H, phenyl or naphthyl;
one Ra is a point of attachment of the first chemical unit to the second chemical unit and the other Ras are H;
Rb at each instance is independently selected from the group consisting of H, deuterium, CF3, C(═O)R1, CN, carbazolyl which is unsubstituted or substituted by one or more R2, Si(R4)3, an alkyl group which is unsubstituted or substituted by one or more R2, an aryl group which is unsubstituted or substituted by one or more R2, and a heteroaryl group which is unsubstituted or substituted by one or more R2;
R1 independently at each instance is an aryl group which is unsubstituted or substituted by one or more R3;
R2 at each instance is independently selected from the group consisting of CF3, C(═O)R1, CN, an alkyl group which is unsubstituted or substituted by one or more R3, an aryl group which is unsubstituted or substituted by one or more R3, and a heteroaryl group which is unsubstituted or substituted by one or more R3;
R3 at each instance is independently selected from the group consisting of an unsubstituted alkyl group, an unsubstituted aryl group and an unsubstituted heteroaryl group;
R4 at each instance is independently selected from the group consisting of an aryl group which is unsubstituted or substituted by one or more R3, and a heteroaryl group which is unsubstituted or substituted by one or more R3;
where two or more of the R1, R2 and R3 substituents together optionally form a monocyclic, polycyclic, aliphatic, aromatic and/or benzofused ring system;
wherein not less than one and not more than three RN2 is phenyl or naphthyl, and wherein at least one of the RN2 which is phenyl or naphthyl is in the ortho position relative to the point of attachment of the chemical unit of Formula N1 to the first chemical unit.
