The present technology relates to multifunctionalized thiol conductor compounds which can be grafted onto polymers, and methods for making same. In certain embodiments, the compounds of the present technology can be grafted onto polymers having low Tg to synthesize single-ion conducting polymer electrolytes having improved conductivity. The multifunctionalized thiol conductor compounds of the present technology generally comprise more than one sulfonamide anion covalently attached to a substitutable core (A) via a sulphide bond, a thiol functional group and optionally a hydrocarbon side chain (L) attached to the substitutable core (A).
