← ScienceWhich risk increases when polymers in flexible OLED screens degrade?
A)Increased singlet oxygen formation
B)Reduced excitonic energy transfer✓
C)Decreased electrode work function
D)Elevated quantum dot aggregation
💡 Explanation
The risk of decreased excitonic energy transfer increases with polymer degradation because chain scission weakens Covalent bonds reducing energy transfer efficiency; therefore excitons can't readily move to the emissive layer; rather than creating light, energy dissipates more through destructive thermal pathways.
