Patent ID: 8614357

Claim:
Spirobifluorene (SBF) derivatives having the following formula: SBF-X wherein: with m=0, 1, 2 or 3; p=positive integer, with (p+1) being the valency of K; n=1; L: is the same or different and independently represents C or PR; Y: is the same or different and independently represents O, S, Se or Te; K: is the same or different and independently represents a chemical bond or a group selected from alkane, alkene, alkyne, aromatic or R substituted aromatic, heteroaromatic or R substituted heteroaromatic or a monocyclic or polycyclic hydrocarbon group; SBF: spiro-compound of formula (I): A, B, C and D: are the same or different and independently represents H, deuterium, F, Cl, Br, I, CN, a linear, branched or cyclic alkyl, alkoxy or thioalkoxy chain with 1 to 40 carbon atoms, which is optionally substituted by R 1 and in which one or more non-neighboring carbon atoms can be replaced by N—R 1 , O, S, C═O, C═S, C═NR 1 , Si(R 1 ) 2 , Ge(R 1 ) 2 , O—CO—O, CO—O, CO—NR 1 , —CR 1 ═CR 1 — or —C≡C— and in which one or more H-atoms is optionally replaced by F, Cl, Br, I or CN, or an aromatic or heteroaromatic ring system with 5 to 40 aromatic ring atoms, which is optionally substituted by deuterium, F, Cl, Br, I, CN or one or more substituents R 1 , or a combination from two, three or four of these systems; two or more substituents R optionally forms a further monocyclic or polycyclic aliphatic or aromatic ring system with each other; R is the same or different and independently represents H, deuterium, F, Cl, Br, I, CN, a linear, branched or cyclic alkyl chain with 1 to 40 carbon atoms, or an aromatic or heteroaromatic ring system with 5 to 40 aromatic ring atoms, which is optionally substituted by deuterium, F, Cl, Br, I, CN or one or more substituents R 1 ; R 1 : is the same or different and independently represents H or an aliphatic or aromatic hydrocarbon ring with 1 to 20 C-atoms; wherein the following compounds are excluded: wherein L, A, B, C and D have the same meaning as above and Ar is the same or different from one another and independently represents a bivalent aromatic or heteroaromatic ring system with 2 to 40 carbon atoms, wherein one or more hydrogen atoms is optionally replaced by F, Cl, Br or I and which is optionally substituted by one or more non-aromatic substituents R; two or more substituents R, A, B, C or D on the same ring as well as on different rings, optionally forms a further monocyclic or polycyclic aliphatic or aromatic ring system with each other.
