https://doi.org/10.1351/goldbook.DT07203

Definition:
Charge-transfer agent used to generate, by oxidation or reduction, positive or negative charges in an intrinsically conducting polymer.

Note: Examples of dopants include AsF5 or I2 as oxidizing agents, generating @C00907@ radicals on the chains of an @IT07208@ (so-called holes), or a solution of sodium naphthalenuidyl in tetrahydrofuran as a reducing agent, generating @A00358@ radicals on the chains of an @IT07208@.
