The ability to control and enhance the response of polyaniline nanofibers to molecules such as hydrogen sulfide is demonstrated through the formation of nanostructured, conducting organic/inorganic hybrid materials. Polyaniline nanofiber composites with transition‐metal chlorides have remarkable responses to hydrogen sulfide that are up to four orders of magnitude greater than the corresponding unmodified nanofibers (see graph).
