Study On The Molecular Design And Synthesis Of The Novel "Suspension-structure" Organic Electroluminescene Material Of Fluoran

Electroluminescene (OEL) is phenomenon in which converts electricity to light. The conversion between electricity and light is an electricity-light domino offect which don't produce heat. The key point to the research on panel-display technology OEL is Organic Electroluminescene (OEL) material and device. Fluoran derivatives are an excellent kind of light-emitting material due to the strong fluorescence and electron-inject peculiarity.The development of research on the key component host light-emitting material of Organic Electroluminescene material, structure of the material was evaluated. Based on the principle of light-emitting materials' luminescene and structure of the material studied, the novel "Suspension-structure" organic electroluminescene materials consisting of host and visitor light-emitting molecules were designed. The fluoran compounds were used as host light-emitting material due to high fluoresce efficiency. The oxadiazole, thiadiazole and carbazole compounds were used as visitor light-emitting material due to strong appetency and ionization.The novel "suspension-structure" organic electroluminescene light-emitting materials were synthesized from host and visitor...
