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.
