THERMALLY ACTIVATED DELAYED FLUORESCENCE MATERIAL, A METHOD OF SYNTHESIZING THE SAME AND AN OLED DEVICE USING THE SAME |
| 摘要 |
The present invention provides a thermally activated delayed fluorescence material, a method of synthesizing the same and an OLED device using the same. The thermally activated delayed fluorescence material includes a structure formula 1 as Ar—(Ar1)m-(Ar2)n, wherein the number of m is in 1˜4, the number of n is in 1˜8, the group Ar is an electron withdrawing group, the group Ar1 is an electron donating group and the group Ar2 is an aggregation induced emission group. The thermally activated delayed fluorescence material has a higher glass transition temperature, high thermal stability and excellent luminous efficiency. The method of synthesizing the same has simplified steps, easily purified product, high yield, and luminous and thermal properties of the product can be adjusted by connecting to differentiated functional groups. |
