The present invention relates to a furanoindolocarbazole derivative, wherein the derivative takes furanoindolocarbazole as the main body, and the general formula of its molecular structure is shown in the general formula (1): The R 1 and R 2 are independently selected from benzene, biphenyl, terphenyl, naphthalene, anthracene, phenanthrene, pyrene, binaphthyl, bianthracene, fluoranthene, benzanthracene, fluorene, benzofluorene, N-phenylcarbamate azole, N-naphthylcarbazole, N-phenylbenzocarbazole, dibenzofuran or dibenzothiophene, the R 1 and R 2 are the same or different. The furanoindolocarbazole derivatives are used in the manufacture of OLED light-emitting devices, and when used as host light-emitting materials or electron transport materials, the external quantum efficiency, power efficiency and current efficiency of the OLED light-emitting devices are greatly improved, thereby improving the efficiency of the OLED light-emitting device. The service life of OLED light-emitting devices is also significantly prolonged, and has a good market prospect. |
