Polycyclic aromatic molecular architectures: MerckRecent Research Landscape

Inefficient charge transfer and narrow color purity in OLEDs limit display brightness and lifespan. These compounds engineer specific molecular energy levels to maximize quantum efficiency and spectral stability.

What technical problems is Merck addressing in Polycyclic aromatic molecular architectures?

Inadequate charge carrier balance

(11)evidences

Organic electroluminescent materials frequently suffer from chemical and thermal degradation during operation. Extending operational stability is critical for commercial viability in display and lighting applications.

Low device operational stability

(10)evidences

Organic electroluminescent materials suffer from rapid chemical degradation during charge transport and recombination. Improving molecular stability under electrical stress extends the operational lifespan of the device.

Insufficient charge carrier stability

(10)evidences

Low charge transport efficiency in organic layers limits the switching speed and brightness of electronic devices. Improving mobility reduces power consumption and enhances device responsiveness.
