Novel blue organic electroluminescent materials with improved hole transporting ability were synthesized by incorporating carbazoles into distyrylarylene (DSA). The new carbazole substituted DSA derivatives (CDSA) were characterized by 1 H NMR, IR, MS and elemental analysis. The luminescent characteristics of CDSA were investigated. Two types of blue light emitting diodes were constructed from CDSA: ITO/NPB/CDSA/PBD/LiF/Al and ITO/CDSA/PBD/LiF/Al.
