Disclosed are electroluminescent devices that comprise organic layers that contain certain organic compounds containing one ore more pyrimidine moieties. The organic compounds containing one ore more pyrimidine moieties are suitable components of blue-emitting, durable, organo-electroluminescent layers. The electroluminescent devices may be employed for full color display panels in for example mobile phones, televisions and personal computer screens.

Electroluminescent device

A daylight illumination system for integration into a building or larger vehicle comprises a translucent facade element () containing a glass sheet and a light redirection element (or), and a light transport channel () for guiding light about horizontally into an interior of the building, the light transport channel comprising one opening attached to the interior side of said facade element and at least one opening towards the interior of the building, characterised in that the light redirection element (or) is formed as a structured polymer film or sheet attached to a glass sheet of the facade element () and is configured for changing the direction of incident light into the about horizontal light transport channel.

Daylighting illumination system
