30.2: Improving Operating Lifetime of Organic Light-Emitting Diodes with Perylene and Derivatives as Aggregating Light-Emitting-Layer Additives

Aggregating PAHs of the perylene class are useful as LEL additives. They greatly improve the device operating half‐life up to 1,000,000 h at the initial luminance of 1540 cd/m2 (20 mA/cm2). There appear to be at least three factors in the lifetime increase: takeover of the LEL functions by the PAHs,...

Description
Summary:Aggregating PAHs of the perylene class are useful as LEL additives. They greatly improve the device operating half‐life up to 1,000,000 h at the initial luminance of 1540 cd/m2 (20 mA/cm2). There appear to be at least three factors in the lifetime increase: takeover of the LEL functions by the PAHs, aggregation, and an expansion of the recombination and/or emission zone.
