Multicomponent organic semiconductor formulations: MerckRecent Research Landscape

Charge carrier mobility instability in organic layers leads to device failure and poor luminosity. Precise control of the molecular dopant-to-host ratio ensures consistent electronic performance and longevity.

What technical problems is Merck addressing in Multicomponent organic semiconductor formulations?

Inadequate organic semiconductor solubility

(8)evidences

Poor electrical connectivity between organic layers and electrodes leads to high power consumption and device failure. Reducing this resistance improves charge injection and overall device efficiency.

Inadequate charge carrier stability

(5)evidences

Organic electroluminescent materials suffer from chemical instability and bond cleavage during device operation. Reducing hydrogen-isotope exchange through deuteration mitigates degradation to extend operational lifespan.

Inconsistent active layer morphology

(3)evidences

Organic electroluminescent materials suffer from rapid chemical and thermal degradation during charge transport. Extending the functional duration of these devices is critical for commercial viability.

Inadequate radiative recombination efficiency

(3)evidences

Imbalanced injection and transport of holes and electrons leads to poor radiative recombination efficiency. Achieving equilibrium between carriers extends device lifespan and reduces power consumption.
