For LEDs based on small molecules, it is rather straightforward to adopt multilayer strategy via layer-by-layer vacuum deposition. However, for polymer-based LEDs, where spin-coating is the basic way to form films, it is very challenging to form multilayer structures, because of solvent erosion of previously deposited layer during spin-coating. We have prepared a series of novel emissive materials which bearing thermally cross-linkable styryl groups (VPC-1, VPC-2, VPOC-1, VPOC-2). Hole transporting layer and emissive layer could be in situ cross-linked under mild thermal polymerization without any initiator. After cross-linking, the resultant films form robust, smooth, and solvent-resistant networks. At the same time, the electrical and optical properties of the cross-linked polymers are preserved and no deleterious species or undesirable byproducts are produced. |
