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(III)], ([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.
