A novel polythiophene derivative containing pyridine side-groups that can react with alkylating agents is prepared and characterized. By attaching the pyridine group to the conjugated backbone, the conductivity of the polymer becomes sensitive to alkylation. By fabricating field-effect transistors with the polythiophene derivative as its channel, a device that can distinguish alkylators from other “innocent” vapors is produced.
