Cationic species as dopants for organic semiconductors

Abstract

Herein a short review of cationic species reported as dopants for organic semiconductors is presented. The approach suggests using the same cationic species for both p-and n-type doping of organic matrices with organic dopants. As an example, pyronin B chloride and benzyl viologen dichloride are reviewed as universal dopants working both ways. Different device characteristics and measurements confirm the donor and acceptor properties of these organic molecules.

“…a main topic in published issues. Huseynova 2,3 reviewed the solutionprocessed electrical doping of organic semiconductors to improve their electrical properties and dopants for the doping of organic semiconductors by cationic species. Kaliyannan et al, 4 gave a full view of the effect of carbon based nanofillers on the properties of elastomers.…”
