The invention relates to an oxidized thieno-bi-carbazole derivative and applications thereof, which belong to the field of organic photoelectric materials. In a compound, an electron withdrawing group -SO- or -SO2- is introduced at 7- and carbazole derivatives are introduced at two ends so as to form the oxidized thieno-bi-carbazole derivative; the general formula of the oxidized thieno-bi-carbazole derivative is as shown in the specification, wherein -SO- or -SO2- has excellent electron transportation performance, thereby enhancing the electron affinity of the compound and the compound stability in air; simultaneously carbazoles with excellent hole transportation performance are introduced at the two ends, so that a transportation material with double polarity is formed. The oxidized thieno-bi-carbazole derivative can serve as a transportation material and a light emitting material of an OLED (Organic Light Emitting Diode) device, and the prepared OLED device has the effect characteristics of high brightness, high efficiency and low voltage. |
