Synthesis and Properties of Novel Derivatives of 1,3,5-Tris(diarylamino)benzenes for Electroluminescent Devices

This is the authors' abstract. We don't add key points for this paper.

Amorphous molecular materials that form stable glasses with high transition temperatures have many applications, including hole-transport materials in light-emitting devices. The synthesis of some novel derivatives of 1,3,5-tris(diarylamino)benzenes, TDABs, with different aryl substituents is reported. The absorption, fluorescence, electrochemical behavior, and thermal properties of these compounds are described and their suitability as hole-transport and emitting materials in light-emitting devices demonstrated.
