Two-aromatic amino terminated dianthracene compound, preparation method and application thereof

Luminescent material prepared from dianthracene compounds substituted by aromatic rings

Method for efficient synthesis of 1, 3, 5-tri(N-phenyl benzimidazole)benzene

Bianthracene compound luminescent material substituted by aromatic ring

Method for preparing 8-hydroxyquinoline metal compounds

characterized by having 50% higher yield than that in literature, simplifying synthesis flow to be suitable for mass production and providing target compound in a purity of greater than 99% to directly prepare DCJTB

characterized by adopting a mixed dehydrating agent containing hydrochloric acid and organic acid, thereby being mild and easy to control, synthesizing a high-purity product and safely discharging waste liquid due to no addition of pollutants

which can be directly used in the next step of the DCJTB synthesis technology without having to be subject to the special purification

characterized by using mild reaction condition and simple method procedures to synthesize high-purity target compound without requiring any special purification, which can be directly used in next reaction step for DCJTB synthesis
