Abstract

The present disclosure belongs to the technical field of organic materials, and provides an organic compound. An adamantane spirofluorenyl and an anthryl are connected to obtain a novel compound for an organic electroluminescence device. In this compound, adamantane in the adamantane spirofluorene greatly increases the density of electron clouds on the fluorenyl through the hyperconjugation effect, which reduces the HOMO energy level of the compound and improves the hole migration ability. Both the adamantane spirofluorene and the anthryl have high hole mobility, so when the two are connected, the overall hole mobility of molecules is further improved, which is beneficial to reducing the working voltage of the device and improving the luminous efficiency. The present disclosure further provides an electronic component and an electronic apparatus including the compound. The organic compound can improve the performance of the electronic component.
