Polymer‐based light emitting diodes constructed from amorphous materials with well‐defined conjugated segments and high glass transition temperatures are reproted. It is shown that grafting 4‐vinyl‐ trans ‐stilbene onto polystyrene results in side‐chain polymers with conjugated segments in the side chains which have amorphous morphologies whereas blends between a conjugated unit and a matrix polymer exhibit unwanted crystallizaion.
