π‐Conjugated polymers bearing nitro substituent(s), e.g., poly(aryleneethynylene) (PAE) type polymers and poly(4,8‐dinitroanthraquinone‐1,5‐diyl) P(4,8‐NO 2 ‐1,5‐AQ), show semiconducting properties with electrical conductivities of an order of 10 −7 to 10 −6 S · cm −1 at room temperature without special oxidation and reduction of the polymer. P(4,8‐NO 2 ‐1,5‐AQ) shows a large shift of phase in alternating current (ac) measurements and a unique magnetism at low temperature.
