An organic electroluminescent device contains an anode, a cathode, and an organic layer containing at least one luminous layer. The organic layer is disposed between the anode and the cathode. At least one luminous layer contains a π-conjugated compound exhibiting no overlap between the electron density distributions of the HOMO and the LUMO in the molecule, such that electron transition between the HOMO and the LUMO occurs by a through-space interaction in the molecule. The π-conjugated compound has a π-conjugated aromatic ring at a moiety on which at least one of the HOMO and the LUMO is localized.
一种有机电致发光器件包含一个阳极、一个阴极和一个含有至少一个发光层的有机层。 有机层位于阳极和阴极之间。 至少一个发光层包含一种π-共轭化合物,其分子中 HOMO 和 LUMO 的电子密度分布没有重叠,因此 HOMO 和 LUMO 之间的电子转换是通过分子中的空间相互作用实现的。 π-共轭化合物具有一个π-共轭芳香环,HOMO 和 LUMO 至少有一个位于该芳香环上。
