Abstract

High efficiency, solution-processed electroluminescent devices are realized using two new red-light-emitting phosphorescent dendrimers (see Figure). By modulating the dendrimer architecture (changing the structure of the luminescent core), tuning of the emission spectra is demonstrated. Processability in organic solvents is achieved by incorporating the red-emitting cores into dendrimers with suitable surface groups and dendrons.
