Photo-cross-linkable polyfluorene-triarylamine (PF-PTAA) copolymer based on the [2 + 2] cycloaddition reaction and its use as hole-transport Layer in OLEDs
We report the synthesis and characterization of a cross-linkable, cinnamic acid functionalized, hole-transporting polyfluorene-triarylamine (PF-PTAA) copolymer. Irradiation with light induces [2 + 2] cycloaddition and renders thin films of this polymer insoluble. Spin-coated films of the polymer and...

| Summary: | We report the synthesis and characterization of a cross-linkable, cinnamic acid functionalized, hole-transporting polyfluorene-triarylamine (PF-PTAA) copolymer. Irradiation with light induces [2 + 2] cycloaddition and renders thin films of this polymer insoluble. Spin-coated films of the polymer and their light-induced cross-linking were investigated by atomic force and electron microscopy. In a proof-of-principle multilayer OLED device the polymer was applied as hole-transport layer (HTL) with commercially available F8BT as emitting layer (EML). Compared to the reference device without HTL we observe a significant increase in OLED performance. These results promise progress in cost-effective large area fabrication of polymer-based multilayer OLEDs with superior performance. |
