Efficient bifunctional materials based on pyrene- and triphenylamine-functionalized dendrimers for electroluminescent devices
© The Royal Society of Chemistry. To realize highly efficient bifunctional blue-light emitting and hole-transporting materials for OLEDs, a series of pyrene- and triphenylamine-peripheral functionalized carbazole dendrimers, namely G1PYR, G2PYR, G1TPA and G2TPA, were designed, synthesized and charac...
