Poly(9-vinylcarbazole), or PVK, is a well-known p-type thermoplastic π-conjugated semiconducting polymer with high thermal and chemical stability, consisting of linear chains of repeated molecular units (CH2-CH)n with pendant 9H-carbazole side groups. It is believed that the electrical conduction in PVK is ruled by both field assisted and temperature activated hopping processes, whereas luminescence occurs via radiative decay of a Frenkel exciton. PVK shows an emission spectrum that covers the entire blue region, owing to the properties of pendant carbazole groups.

PVK has been widely used as a hole-transporting and an electron-blocking layer, host polymer for hole-transporting molecules in OLEDs to enhance the native hole-transporting properties, and blue emitting layer material. It has also been used as photoconductive layers in the xerographic industry and memory devices. PVK, as a non-conjugated polymer, shows unique optical properties and hole transport properties in application of organic electronics due to its hydrophobicity, large hole mobility, solution processability, and stability.
