Amplified spontaneous emission with unprecedented gain values is demonstrated from thin films of novel blue‐light‐emitting indenofluorene‐phenanthrene copolymers. In addition to their excellent photoluminescence properties, high charge‐carrier mobilities are observed, which makes these copolymers very promising for organic light amplifiers and lasers.
