Abstract

Abstract We report on an efficient and facile synthesis of up to 4 th generation carbazole dendrons by using a mild Ullmann coupling reaction. The dendrimers, namely GnC (n= 1– 4), are thermally stable amorphous materials with high glass transition temperatures (T g) up to 347 C and exhibit chemically stable redox properties. The compounds show great potential to work as solution-processed hole-transporting materials for electroluminescent ...
