The present invention relates to a compound of the formula (I)
wherein all of R
1
to R
11
, except one, are independently selected from the group consisting of H, D, F, substituted or unsubstituted C
1
to C
18
alkyl, substituted or unsubstituted C
6
to C
42
aryl, substituted or unsubstituted C
3
to C
42
heteroaryl; and adjacent groups R
1
to R
11
may be linked to each other to form a fused ring,
wherein the one of R
1
to R
11
not selected from the above groups is a group G, wherein
the group G comprises one atom A having an electron pair in a p-orbital thereof;
the group G comprises two 6-membered aryl rings which are attached to the atom A, wherein each of the two 6-membered aryl rings is attached to the atom A via a single bond respectively; and wherein the two 6-membered aryl rings attached to the atom A may be connected with each other via a single bond;
the group G comprises 12 to 66 carbon atoms in total;
the group G is attached to the benzoacridine part of the compound of formula (I) via a single bond or via a C
6
to C
18
arylene group, wherein the C
6
to C
18
arylene group is part of the group G; and
the group G is unsubstituted or substituted with one or more substituents independently selected from the group consisting of D, F, C

to C
18
arylene group, wherein the C
6
to C
18
arylene group is part of the group G′ provided that in case that the group G is attached to the benzacridine part of the compound of formula (I) via the C
6
to C
18
arylene group, substituents which may be attached to the C
6
to C
18
arylene group are only selected from the group consisting of C
