poly(N-vinyl carbazole)

Poly(N-vinyl carbazole) is a rigid aromatic polymer synthesized from N-vinyl carbazole monomers, forming a conjugated backbone with excellent thermal stability and electron-transport properties. It is primarily used in optoelectronic and photonic device applications, particularly as a hole-transport material in organic light-emitting diodes (OLEDs), organic photovoltaics, and perovskite solar cells, where its high glass transition temperature and electrical properties enable stable device performance. The material is notable for enabling efficient charge carrier mobility in organic semiconductor stacks and is preferred over smaller-molecule alternatives in applications requiring film durability and processing flexibility.
