Organic light-emitting diode (OLED) comprising cathode, anode and at least one emitting layer which comprises as host material at least one organic compound which has atropisomerism and is thus capable of the formation of diastereomers, characterised in that the compound that has atropisomerism is a compound of the formula where the following applies to the symbols and indices: A stands for a 9,10-linked anthracene unit, which may be substituted by R or unsubstituted; B, C, D, E, G, J are on each occurrence, identically or differently, an aromatic or heteroaromatic ring system having 5 to 40 aromatic ring atoms, which may be unsubstituted or substituted by one or more radicals R, with the proviso that a group R is bonded in at least one ortho-position to the link to A, or that this position is blocked by a part of the ring system if B, C, D, E, G or J represents a condensed aromatic ring system; R is on each occurrence, identically or differently, F, Cl, Br, I, a straight-chain alkyl or alkoxy chain having 1 to 40 C atoms or a branched or cyclic alkyl or alkoxy chain having 3 to 40 C atoms, which may in each case be substituted by R 1, in which, in addition, one or more non-adjacent C atoms may be replaced by N-R 1, O, S, C=O, O-CO-O, CO-O, SO, SO 2, P(=O)R 1, Si(R 1) 2, -CR 1 =CR 1 - or -C≡C- and in which, in addition, one or more H atoms may be replaced by F, Cl, Br, I or CN, or an aromatic or heteroaromatic ring system having 5 to 40 aromatic ring atoms, which may in addition be substituted by one or more radicals R 1, or a combination of two, three, four or five of these systems; two or more radicals R here may also form a further mono- or polycyclic, aliphatic or aromatic ring system with one another; R 1 is on each occurrence, identically or differently, H or an aliphatic or aromatic hydrocarbon radical having 1 to 20 C atoms; n is on each occurrence, identically or differently, 0 or 1; m is on each occurrence, identically or differently, 1, 2, 3, 4 or 5; and an atropisomeric excess of at least 70% is present and the atropisomerism is generated by hindered rotation about C-C single bonds.
