Claims14
Compound of the Formula (I)
- wherein all of R1 to R11, except one, are independently selected from the group consisting of H, D, F, substituted or unsubstituted C1 to C18 alkyl, substituted or unsubstituted C6 to C42 aryl, substituted or unsubstituted C3 to C42 heteroaryl;
- and adjacent groups R1 to R11 may be linked to each other to form a fused ring,
- wherein the one of R1 to R11 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 C6 to C18 arylene group, wherein the C6 to C18 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, C1 to C18 alkyl, C6 to C42 aryl, C6 to C42 heteroaryl, (R12)2P═O, CN or G′, wherein the group G′ is defined likewise group G with the exception that the group G′ is not attached to the benzoacridine part of the compound of formula (I) but to the group G via a single bond or via a C6 to C18 arylene group, wherein the C6 to C18 arylene group is part of the group G′ provided that in case that the group G is attached to the benzoacridine part of the compound of formula (I) via the C6 to C18 arylene group, substituents which may be attached to the C6 to C18 arylene group are only selected from the group consisting of C1 to C18 alkyl, C6 to C42 aryl, (R12)2P═O and CN;
- wherein in case that at least one of R1 to R11, which is not the group G, is substituted, the respective substituent or substituents are independently selected from the group consisting of D, F, C1 to C18 alkyl, C6 to C36 aryl, C6 to C42 heteroaryl, (R12)2P═O, CN;
- and
- wherein R12 are independently selected from the group consisting of C1 to C18 alkyl and C6 to C24 aryl;
- wherein the group G comprises the following structural element
- wherein
- the group G is attached to the benzoacridine part of the compound of Formula (I) at the position indicated by “#”, wherein
- the two 6-membered aryl rings may be linked with each other via a single bond.
