Fluoranthene derivatives of the general formula I
where the symbols have the following meanings:
R
1
, R
2
, R
3
, R
4
, R
5
are each hydrogen, alkyl, an aromatic radical, a fused aromatic ring system, a heteroaromatic radical or —CH═CH
2
, (E)- or (Z)-CH═CH—C
6
H
5
, acryloyl, methacryloyl, methylstyryl, —O—CH═CH
2
or glycidyl;
where at least one of the radicals R
1
, R
2
and/or R
3
is not hydrogen;
X is an alkyl radical, an aromatic radical, a fused aromatic ring system, a heteroaromatic radical or a radical of the formula (I′)
or an oligophenyl group; n is from 1 to 10 or, in the case of X=oligophenyl group, 1-20;
with the proviso that R

are hydrogen. Furthermore, the invention relates to a process for preparing them and the use of fluoranthene derivatives as emitter molecule in organic light-emitting diodes (OLEDs), a light-emitting layer comprising the fluoranthene derivatives of the invention as emitter molecules, an OLED comprising the light-emitting layer of the invention and devices comprising the OLED of the invention.
通式I的芴衍生物,其中符号具有以下含义:
R1、R2、R3、R4、R5分别为氢、烷基、芳基、融合芳环系统、杂芳基或—CH═CH2,(E)-或(Z)-CH═CH—C6H5,丙烯酰基,甲基丙烯酰基,甲基苯乙烯基,—O—CH═CH2或环氧丙烷基;
其中至少一个基团R1、R2和/或R3不是氢;
X为烷基、芳基、融合芳环系统、杂芳基或式(I′)的基团或寡苯基团;n为1到10或在X=寡苯基团的情况下为1-20;
但要注意当R4和R5为氢时,R1、R2、R3和X不能同时为苯基。此外,本发明还涉及制备它们的方法以及将芴衍生物用作有机发光二极管(OLED)中的发射分子,包含本发明的芴衍生物作为发射分子的发光层,包括本发明的发光层的OLED和包括本发明的OLED的设备。
