S,S-dioxo-dibenzothiophene and phenanthroimidazole based small molecule and application thereof in electroluminescent devices

The invention discloses an S,S-dioxo-dibenzothiophene and phenanthroimidazole based small molecule and application thereof in electroluminescent devices. Phenanthroimidazole is used as a donor unit, S,S-dioxo-dibenzothiophene is used as an acceptor unit, and a novel donor-acceptor type blue fluorescent molecule is constructed. The molecule has the characteristics of S,S-dioxo-dibenzothiophene suchas wide band gap, high fluorescence quantum yield, strong electron affinity, high electron mobility, and also has the characteristics of phenanthroimidazole such as large conjugate rigid structure, bipolar transmission, and the like. The molecule has an asymmetric structure, and can inhibit molecular aggregation and reduce exciton quenching. In addition, the emission spectrum can be adjusted by changing the connection sites of the two units. The small molecule can be used for preparing high-efficiency blue light organic electroluminescent devices with different emission wavelengths.

Luminescent material with naphthoindene carbazole unit containing polar substituent, and preparation and application of luminescent material

The invention belongs to the technical field of organic photoelectricity and discloses a luminescent material with a naphthoindene carbazole unit containing a polar substituent, and a preparation andapplication of the luminescent material. The luminescent material has a structure shown in the description. The luminescent material taking the naphthoindene carbazole unit containing the polar substituent as the center is obtained by taking the naphthoindene carbazole unit containing the polar substituent as a core and selecting a unit having an electron-transport property. The naphthoindene carbazole unit has strong chemical stability and chemical modification performance, and can undergo a variety of chemical reactions. The presence of lone pair electrons on a nitrogen atom, gives the naphthoindene carbazole unit better hole injection and transport properties. The naphthoindene carbazole unit is good in flatness, has high fluorescence quantum efficiency, and is conducive to improve thephotoelectric properties of the material. The luminescent material can be dissolved in polar solvents such as methanol, DMF, DMSO and water. The luminescent material prepared by the invention can be used to prepare a light-emitting layer of a light-emitting diode by a solution processing technology such as spin coating, ink-jet printing or printing film forming.
