Abstract

An organic molecules for use in optoelectronic devices is disclosed having a structure of formula A1:where A, RN, Ra and R2 are as defined herein.

First claim

The invention claimed is:

1. An organic molecule comprising a structure of Formula A1:

where
A at each instance is independently CR b or N;
R N is methyl, phenyl, xylyl, mesityl, naphthyl, biphenyl, naphthylphenyl, terphenyl or 2,4,6-triphenylphenyl;
R a at each instance is independently H, deuterium, an alkyl group or an aryl group;

R b at each instance is independently selected from the group consisting of:
H,
deuterium,
CF 3 ,
C(═O)R 1 ,
CN,
an alkyl group which is unsubstituted or substituted by one or more R 2 ,
an aryl group which is unsubstituted or substituted by one or more R 2 and is optionally additionally substituted by one or more unsubstituted alkyl groups and/or by one or more unsubstituted or alkyl-substituted aryl groups,
a heteroaryl group which is unsubstituted or substituted by R 2 and/or by one or more unsubstituted alkyl groups and/or by one or more unsubstituted or alkyl-substituted aryl groups and
a group of the sub-formula T1 or a group of the sub-formula T2:

where:

R N2 is an alkyl group, an aryl group which is unsubstituted or substituted by one or more R N3 or a heteroaryl group which is unsubstituted or substituted by one or more R N3 ;
R N3 is an alkyl group, an aryl group or a heteroaryl group;
R 1 at each instance is an aryl group which is unsubstituted or substituted by one or more R 2 ;
R 2 at each instance is independently F, CF 3 or CN;

where one to four A are N or at least one R b is selected from the group consisting of:
CF 3 ,
C(═O)R 1 ,
CN,
an alkyl group substituted by one or more R 2 ,
an aryl group substituted by one or more R 2 , and optionally additionally substituted by one or more unsubstituted alkyl groups and/or by one or more unsubstituted or alkyl-substituted aryl groups,
a heteroaryl group which is unsubstituted or substituted by one or more R 2 and/or by one or more unsubstituted alkyl groups and/or by one or more unsubstituted or alkyl-substituted aryl groups and
a group of the sub-formula T1 or a group of the sub-formula T2:

and where # indicates the point via which the group of the sub-formula T1 or T2 is attached via a single bond.

2. The organic molecule according to claim 1 , comprising a structure of Formula A2:

where
R c at each instance is independently selected from the group consisting of:
CF 3 ,
C(═O)R 1 ,
CN,
an alkyl group substituted by one or more R 2 ,
an aryl group substituted by one or more R 2 , and optionally additionally substituted by one or more unsubstituted alkyl groups and/or by one or more unsubstituted or alkyl-substituted aryl groups,
a heteroaryl group which is unsubstituted or substituted by one or more R 2 and/or by one or more unsubstituted alkyl groups and/or by one or more unsubstituted or alkyl-substituted aryl groups and
a group of the sub-formula T1 or a group of the sub-formula T2:

where R N2 is an alkyl group, an aryl group which is unsubstituted or substituted by one or more R N3 or a heteroaryl group which is unsubstituted or substituted by one or more R N3 ;

R d at each instance is independently selected from the group consisting of:
H,
deuterium,
CF 3 ,
C(═O)R 1 ,
CN,
an alkyl group which is unsubstituted or substituted by one or more R 2 ,
an aryl group which is unsubstituted or substituted by one or more R 2 and/or by one or more unsubstituted alkyl groups and/or by one or more unsubstituted or alkyl-substituted aryl groups,
a heteroaryl group which is unsubstituted or substituted by one or more R 2 and/or by one or more unsubstituted alkyl groups and/or by one or more unsubstituted or alkyl-substituted aryl groups, and
a group of the sub-formula T1 or a group of the sub-formula T2:

where R N2 is an alkyl group, an aryl group which is unsubstituted or substituted by one or more R N3 or a heteroaryl group which is unsubstituted or substituted by one or more R N3 ;

and #, R a , R 1 , R 2 and R N3 have the aforestated meanings.

3. The organic molecule according to claim 1 , comprising a structure of Formula A3:

where
R c at each instance is independently selected from the group consisting of:
