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.

将开发分子有序的3D发射器网络，以同时实现两个概念，以提高OLED的外耦合。通过排列发射体分子的取向，将控制分子跃迁偶极矩的方向，从而控制它们的优先发射方向。通过引入手性发射体分子，例如对环芳，产生圆偏振电致发光，其可以无损耗地通过外部偏振器，通常用于提高OLED显示器的对比度。因此，可以将外耦合效率提高两倍。
