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 0078; 0079; 0080; 0081, (2018/11/22)
The invention discloses a compound for preparing an organic electroluminescent material, and belongs to the technical field of electroluminescent materials. A synthesis method of the compound comprises the following steps that with 9-phenyl-3,6-dibromo carbazole as a raw material, a brominated carbazole group is obtained through Ullmann coupling, and reacts with n-butyllithium and trimethyl borateat minus 78 DEG C to obtain carbazole boric acid. The compound and brominated electron acceptor materials are subjected to a Suzuki coupling reaction so that the bipolar electroluminescent material containing the carbazole group can be obtained, conveying of charge carriers is regulated and balanced through double electron withdrawing groups of the main material, and therefore the quenching effect is suppressed. The compound can be used for synthesizing the main electroluminescent material. Further, the invention provides a method for synthesizing the bipolar electroluminescent material.

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.

Paragraph 0092-0094; 0095, (2019/01/14)
The invention relates to a preparation method and application of a bipolar electroluminescent material comprising carbazole groups, which belongs to the technical field of electroluminescence. The bipolar material adopts 3,9'-bicarbazole as an electron donating group, different n-type groups are connected on a site 2 and site 6 of the group to obtain the compound. Electron absorbing groups comprises 3-cyanopyridine, 3-diphenylphosphonyl pyridine, 5-pyrazolyl pyridine, 5-(1,2,4-triazolyl)pyridine and 3,3'-dipyridyl. According to the bipolar electroluminescent material comprising carbazole groups, the transport of a current carrier is controlled and balanced by virtue of double electron absorption groups of the main body material, so that the quenching effect can be inhibited. The bipolar electroluminescent material can be used as the main body material of a luminescent layer to be applied to an electroluminescent device.
