Benzimidazole derivative molecular architecture: MerckRecent Research Landscape

Exciton quenching and thermal instability in thin-film layers reduce device lifespan and brightness. Precise molecular engineering of the emissive layer composition stabilizes charge transport to extend operational durability.

What technical problems is Merck addressing in Benzimidazole derivative molecular architecture?

Low electroluminescent efficiency

(19)evidences

Suboptimal charge injection and transport in organic layers lead to high driving voltages and poor luminous efficiency. Achieving precise electrical equilibrium extends device operational lifespan.

Insufficient charge carrier stability

(6)evidences

Poor synchronization of electron and hole transport leads to non-radiative recombination and rapid device aging. Achieving equilibrium in the recombination zone extends operational lifespan and increases quantum efficiency.
