A novel material based on polyaniline doped with [Cs] [In(dmit)2], (cesium) [bis(1,3-dithiole-2-thione-4,5-dithiolato)indium (III)]

A novel conducting hybrid material based on polyaniline doped with a monoanion derived from [cesium] [bis(1,3-dithiole-2-thione-4,5-dithiolato)indium(Ill)], ([Cs][In(dmit)(2)]), is reported. Fourier transform infrared (FTIR), UV-vis and X-ray photoelectron spectroscopies showed that the [Cs][In(dmit)(2)] acts as the doping agent for the emeraldine base (insulating form of the polyaniline). This new material presents lower resistivity than the starting materials, and forms a flexible, self-supporting film with good homogeneity, which is an important feature for the development of new devices to be useful in the electroelectronic industries.
