- Fluorene-containing aryl amine compound and organic electroluminescent device thereof
-
The invention provides a fluorene-containing aryl amine compound and an organic electroluminescent device thereof, and belongs to the technical field of organic photoelectric materials. To improve thebalance of charges in a light-emitting layer and avoid interface luminescence of a hole transport layer, the invention provides a fluorene-containing aryl amine compound, which has a proper HOMO value and T1 value and a good hole transport performance; and the fluorene-containing aryl amine compound can improve the luminous efficiency of a device and prolong the service life of the device when being applied to the OLED device as a hole transport layer, and is an OLED material with excellent photoelectric properties.

- A new cross-linkable 9,10-diphenylanthracene derivative as a wide bandgap host for solution-processed organic light-emitting diodes
-
Efficient organic light-emitting diodes (OLEDs) can be obtained using multilayered architectures where the processes of charge injection, transport and recombination are separated and optimized in each layer. Processing these structures from solution requires strategies to avoid redissolution or damage of the previously deposited layers. Several reports have demonstrated the development of cross-linkable hole transport materials, while less literature describes the synthesis and applications of such wide bandgap host materials for multilayered OLEDs. In this work we introduce a cross-linkable derivative of 9-(4-(10-phenylanthracene-9-yl)phenyl)-9H-carbazole incorporating styrene moieties (SPhPC) which can be efficiently cross-linked via radical polymerization. We present the synthesis and characterization of SPhPC, as well as its application as the host in the light-emitting layer to prove the concept of solution processed blue OLEDs.
