Polythiophene-based sensors types

We had initially limited our studies to polypyrrole based sensors with several different chemically inert VOCs and to polythiophene sensors with toluene analyte. However, because of the relatively low sensitivity of the polypyrrole sensors and because of photosensitivity of the polythiophene sensors we have recently directed our attention to a new type of oligomer of aniline which we have recently synthesized and characterized (67, 62).
