  • [7,8-(ER 2) 2-7,8-C 2B 9(R 1) 10] Wherein;

    '"'"'s P, As, Sb, N or P=O, P=S, As=O or As=S group when E occurs at every turn identical or differently;

    '"'"'s H, deuterium, F, Cl, Br, I, N (R when R occurs at every turn identical or differently 2) 2, have straight chained alkyl, alkoxyl group or the thio alkoxy group of 1 to 40 C atom or have side chain or cyclic alkyl, alkoxyl group or the thio alkoxy group of 3 to 40 C atoms, they separately can be by one or more radicals R 2Replace the CH of wherein one or more non-vicinities 2Group can be by R 2C=CR 2, C ≡

    C, Si (R 2) 2, Ge (R 2) 2, Sn (R 2) 2, C=O, C=S, C=Se, C=NR 2, P (=O) (R 2), SO, SO 2, NR 2, O, S or CONR 2Alternative and wherein one or more H atoms can be by F, Cl, Br, I, CN or NO 2Substitute, perhaps have the aromatics or the heteroaromatic rings system of 5 to 60 aromatic ring atoms, described member ring systems in each case can be by one or more radicals R 2Replace, perhaps have the aryloxy or the heteroaryloxy group of 5 to 60 aromatic ring atoms, described group can be by one or more radicals R 2Replace the perhaps combination of these systems;

    Two or more described substituent R can also form list or polycyclic, aliphatic series, member ring systems aromatics and/or benzo-fused each other herein;
