AI Technical Summary

Technical Problem

The efficiency and life of blue organic electroluminescent devices are difficult to improve. The existing luminescent auxiliary layer materials cannot effectively block excitons under high current density, resulting in offsetting of the composite region, reducing efficiency and shorter life.

Method used

An amine-based organic compound with a specific structure is used as the luminescence auxiliary layer material, with excellent exciton blocking ability and hole mobility at high current density, and is used for the hole transport region and the luminescence auxiliary layer of organic electroluminescent devices.

Benefits of technology

It improves the efficiency and life of organic electroluminescent devices, ensures carrier balance, prevents the composite region from shifting to the hole side, and extends the service life of the device.
