Stable blue electroluminescence from polyfluorene light‐emitting devices with dendron side chains is demonstrated. A detailed photophysical characterization of the material including photoinduced absorption data is given. Color coordinates of (0.189,0.237) and luminances of more than 380 cd m –2 can be obtained with these devices. The Figure shows the chemical structure of the dendronic polyfluorene.
