High‐efficiency light‐emitting diodes (LEDs) using air‐stable electrodes remain an important goal. Here the authors report the design and synthesis of electroluminescent hybrid organic–inorganic materials using the sol‐gel process in order to improve the aging and environmental stability of LEDs. Devices—which emitted in the orange—consisting of a sol‐gel layer sandwiched between a transparent indium tin oxide (ITO) electrode and an evaporated aluminum cathode were also prepared, demonstrating the electroluminescent properties of the sol‐gel materials.
