  • Patent number: 11492314
    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.

  • Patent number: 11444252
    Abstract: The present disclosure relates to the technical field of organic materials, and provided therein is a nitrogen-containing compound, comprising at least three directly or indirectly linked fused ring systems. A first fused ring system is a fluorenyl group spiro-linked by adamantane, and adamantyl can greatly increase the electron cloud density of a conjugated structure of the first fused ring system by means of a hyperconjugation effect, which can increase hole mobility. The three fused ring systems enable the nitrogen-containing compound of the present disclosure to have a high first triplet energy level so that the nitrogen-containing compound of the present disclosure is suitable as the host material of an organic light-emitting layer in an organic electroluminescent device.
