Paragraph 0028; 0030-0033, (2018/09/28)
The invention discloses an organic electroluminescent material and application thereof. The organic electroluminescent material is a compound with a structure shown as a formula I. The compound is a bipolar main body material with high efficiency and slow attenuation. Compared with almost small molecular materials recorded in the prior art, the compound m-BPySCz is slowly attenuated in a blue-light device and a green-light device under high brightness. Therefore, the organic electroluminescent material has a wide application prospect in preparation of electroluminescent devices. The formula Iis shown in the description.

Paragraph 0046; 0078; 0079; 0080; 0081, (2019/01/07)
The invention discloses a substrate material for preparing a bipolar electroluminescent material, and belongs to the technical field of electroluminescence. A synthesis method of the substrate material comprises the steps: using 3,9'-dicarbazole as a raw material, performing Ullmann coupling to obtain brominated carbazole groups, and performing a reaction between the brominated carbazole group with n-butyllithium and trimethyl borate at -78 DEG C so as to obtain carbazole boronic acid. The bipolar electroluminescent material containing the carbazole groups can be obtained by performing a Suzuki coupling reaction between the substrate material and the brominated electron acceptor material, the adopted 3-carbazolylcarbazole has a good hole transport ability, and a high triplet energy level can be maintained by using the substrate material to synthesize the bipolar host material containing the carbazole groups, so that effective energy transfer from a host to a guest is ensured, and carrier injection and transmission ability of an electroluminescent device are improved.
