(A) in addition to the triplet-emitter structural elements contain carbazole, bridged carbazole-dimer, ketone, phosphinoxide, sulfoxide, sulfone or silane. The amount of (I) in (A) is 5 mol.%. (I) is used as polymer base and/or used in combination with a polymer base, where p is 0. (I) is used as light transporting unit, where p is 0-1 (where at least one p is 1), o is 0-2 (where o is 0, when p is 1) and X is N-Ar. (I) is used as emitter, where p is 0-1 (where at least one p is 1), o is 0-2 (where o is 0, when p is 1) and X is -CR1=CR1-, -C?=C- or N-Ar, where at least one X is -CR1=CR1- or -C?=C-). Preferred Composition: The blend comprises a compound that emits light from the triplet condition at the room temperature. Preferred Definitions:    R = H, 1-10C alkyl, branched or cyclic 3-10C alkyl (where one or more non-adjacent C-atom is replaced with -CH=CH- or -C?=C- and one or more H is replaced with F or CN) or (hetero)aromatic ring system with 5-20 aromatic ring atom (substituted with one or more non-aromatic R1, both R can form a further ring system provided that at least one R is not H) (preferably one R residue is H and other R residue is (hetero)aromatic ring system with 5-15 aromatic ring atom);    Y1 = bivalent, (hetero)aromatic ring system having 5-20 aromatic ring atom (optionally substituted with R1);    Ar = monovalent, (hetero)aromatic ring system having 5-20 aromatic ring atom (optionally substituted with R1);    R1 = H, F, N(R2)2, 1-10C alkyl, branched 3-10C alkyl (where one or more non-adjacent C-atom is replaced with -CR1-CR1- or -C?=C- and one or more H is replaced with F) or (hetero)aryl with 5-20 aromatic ring atoms (which is substituted with non-aromatic R1 and two or more R1 together forms a ring system);    n = 0;    m = 0-2; and    o = 0-1.    SPECIFIC COMPOUNDS - The use of 2,4,2',4'-tetramethyl-(1,1')binaphthalenyl, 4,4'-dibromo-2,3,2',3'-tetramethyl-(1,1')binaphthalenyl, 1-(2'-acetyl-4,4'-dibromo-(1,1')binaphthalenyl-2-yl)-ethanone and 4,4'-dibromo-2,2'-dimethyl-(1,1')binaphthalenyl is specifically claimed as (II).    EXAMPLE - 2,2'-Dimethyl binaphthyl (59.2 g) was dissolved in trichloromethane (1000 ml) and cooled to 5degreesC. A solution of bromine (20 ml) in trichloromethane (90 ml) was added within 1 hour. After 1 hour, saturated sodium sulfate (180 ml) was added and worked up to give 4,4'-dibromo-2,2'-dimethyl-1,1'-binaphthyl (50.9 g). Magnesium (5.8 g), 4,4'-dibromo-2,2'-dimethyl-1,1'-binaphthyl (50.8 g) in tetrahydrofuran (340 ml) was mixed and after 3 hours, the solution was cooled and to this solution, boric acid trimethyl ester (38 ml) in tetrahydrofuran (250 ml) at -75degreesC was added. The reaction mixture was stirred for 6 hours followed by the addition of ethyl acetate (100 ml), acetic acid (30 ml) and water (60 ml). The organic phase was separated, washed with water and dried over sodium sulfate. The solid material was suspended in toluol (200 ml) and water free ethylene glycol (12.5 ml) was added and the suspension was worked up to give 4,4'-(2-(1,3,2)dioxaborolanyl)-2,2'-dimethyl-1,1'-binaphthyl (67.5 g).
