Highly Cross-Linked Polymers for Functional Organic Multi-Layers (C02)

分子有序的3D发射极网络将被开发，以同时使两个概念能够改善OLED的输出耦合。通过对齐发射体分子的取向，可以控制分子跃迁偶极矩的方向，从而控制分子的优先发射方向。通过引入手性发射体分子，如对环芳烃，产生圆偏振电致发光，它可以无损失地通过外部偏振器，通常用于提高OLED显示器的对比度。因此，可以将输出耦合效率提高两倍。

Molecularly ordered 3D emitter networks will be developed to simultaneously enable two concepts to improve the outcoupling of OLEDs. By aligning the orientation of emitter molecules, the direction of the molecular transition dipole moments and thus their preferential emission direction will be controlled. By introducing chiral emitter molecules, such as paracyclophanes, circularly polarised electroluminescence is generated, which can pass without loss through external polarisers, commonly used to improve the contrast of OLED displays. Thus, the outcoupling efficiency can be improved two-fold.
