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 dam...

Description
Summary: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)-9 H -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. We present a cross-linkable wide bandgap host based on 9-(4-(10-phenylanthracene-9-yl)phenyl)-9 H -carbazole.
