Publication number: 20240130219Abstract: Provided is an organic electroluminescent device and an application thereof. The organic electroluminescent device includes a metal complex having a substituent A capable of reducing a maximum capacitance in the device, and the metal complex can be used as an emissive material in an emissive layer of the electroluminescent device. The device including a metal complex having the substituent A can obtain a decrease in the maximum capacitance of the device, thereby improving the response time and refresh frequency of an OLED display device at a low grayscale. In another aspect, the substituent A can cause a decrease in the maximum capacitance of the device, and the device prepared with the metal complex including the substituent A can still maintain excellent device performance compared with the devices prepared with the metal complexes that do not include the substituent A. Further provided is an electronic assembly including the organic electroluminescent device.Type: ApplicationFiled: September 22, 2023Publication date: April 18, 2024Applicant: BEIJING SUMMER SPROUT TECHNOLOGY CO., LTD.Inventors: Zhen Wang, Hongbo Li, Wei Cai, Zheng Wang, Jing Wang, Ying Hou, Chi Yuen Raymond Kwong, Chuanjun Xia
