Poly(N-vinylcarbazole) (PVK) is a well-established p-type thermoplastic π-conjugated semiconducting polymer renowned for its high thermal and chemical stability. Featuring pendant 9H-carbazole side groups, PVK serves as an efficient hole-transporting and electron-blocking layer, as well as a host polymer for hole-transporting molecules in OLEDs to enhance device performance. It has also been widely utilized as a blue-emitting layer in PLEDs, photoconductive layers in xerographic applications, and in memory devices. PVK’s hydrophobicity, high hole mobility, solution processability, and stability make it highly versatile. Its conduction is governed by field-assisted and thermally activated hopping, while luminescence arises from radiative Frenkel exciton decay, producing broad blue emission.
