A phosphorescent poly(dendrimer) with increased viscosity for solution-processed OLED devices

Abstract:

We describe a phosphorescent green solution-processable iridium(III) complex containing poly(dendrimer), where the polymer character enhances compatibility with ink-jet printing techniques while the dendritic structure improves solid-state performance. The poly(dendrimer) shows an increased viscosity in chlorobenzene solutions of 1.1 mPa s at 25 mg/ml concentration relative to a simple first generation dendrimer. The poly(dendrimer) has a photoluminescence quantum yield of 15% in a neat film ...
