Organic material for an electronic optoelectronic device and electronic device comprising the organic material

A compound for an electroluminescent device having the structure:

• wherein
• R1 to R5 are independently a substituted or unsubstituted C6 to C30 aryl group or a substituted or unsubstituted C2 to C30 heteroaryl group, wherein at least two of R1, R2, R3, R4, R5 and L are in ortho-Position to each other at the benzene ring B
• a to e are independently from each other 0 or 1 and 2≤a+b+c+d+e≤5;
• A is a C10 to C20 arylene group with at least two fused aryl rings;
• L and L′ are independently selected from each other a C2 to C30 heteroaryl group or C6 to C20 aryl group
• n is 1 or 2;
• m is 0, 1 or 2,
• wherein when n or m are 2 then each of the both L and/or L′ can be different from the other;
• and
• R is selected from substituted or unsubstituted C2 to C30 heteroaryl group or CN, wherein R is not substituted or unsubstituted dibenzofuranyl.
