Description

technical field

[0001] The present application relates to a method for preparing coronene compounds, belonging to the field of organic chemistry. Background technique

[0002] Coronene compounds are polycyclic aromatic hydrocarbon compounds with highly symmetrical structures, with large conjugated system, strong rigid structure and coplanarity. The maximum absorption wavelength of coronene is 255nm, the maximum emission wavelength is 520nm, and it has a very high fluorescence quantum efficiency. Therefore, it occupies an extremely important position in the field of fluorescent materials, especially in the field of ultraviolet fluorescent materials. Coronene compounds are excellent materials for preparing Ultraviolet Charge Coupled Device (UV-CCD), and UV-CCD image sensors are widely used in nuclear explosion, medicine, astronomy and military (radar) and other fields.

[0003] At present, the preparation methods of coronene mainly include three kinds, namely Wurtz-Fittig rea...
