titleOfInvention | A kind of imidazole blue light material containing spirobifluorene, crystal and preparation method |
abstract | The invention belongs to the field of organic electroluminescence devices, and in particular relates to a spirobifluorene-containing imidazole blue light material, a crystal and a preparation method. The invention provides a spirobifluorene-containing imidazole blue light material, which is: phenanthroimidazole derivatives or pyreneimidazole derivatives; the invention also provides the above phenanthroimidazole derivatives and pyreneimidazole A preparation method of a class derivative; the present invention also provides a preparation method of the above imidazole class blue light material crystal. The material prepared by the invention has a regular structure after the single crystal is prepared, and the prepared material has stable thermodynamic properties, low start-up voltage, low efficiency roll-off effect and high fluorescence internal quantum efficiency, and is a It is a very good blue light material, which can be widely used in the preparation of controllable light-emitting devices; it solves the lack of a stable thermodynamic property, low start-up voltage, low efficiency roll-off effect and high internal fluorescence in the prior art. Technical shortcomings of quantum-efficient blue-light materials. |
