Synthesis and functional properties of star-burst dendrimers that contain carbazole as peripheral edges and triazine as a central core

With the aim of combining the electron and hole-transporting moieties into one molecule and to continue our investigation into the structure?property correlations of dendrimers, two novel star-burst dendrimers 1 and 2 constructed with carbazoles as the peripheral hole-transporting moieties and one triazine moiety as an electron-transporting central core, have been synthesized. The convergent synthetic approach uses palladium-catalyzed Suzuki cross-coupling as a key reaction. Their functional properties have also been investigated.
