General description

Poly(9-vinylcarbazole) (PVK) is a conductive polymer which is mainly used as a hole transporting medium at high efficiencies with low driving voltage. It can also be used as an anode for hole injection and can act as an effective charge transferring gate by co-doping it with organic dyes.

Application

PVK:graphene oxide composite can be used as a hybrid film which can be coated on silica substrate for the fabrication of organic field effect transistors (OFETs). It can also form a nano-composite film with carbon nanospheres (CNS) which can be potentially used in supercapacitors and sensor based applications.


The application for Poly(9-vinylcarbazole) is primarily in the development of organic light-emitting diodes (OLEDs) and as a photoconductive material in electronic devices.
