Polythiophene-based sensors chemical

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). 

New sensors have also been developed for chemical nerve agents and nerve agent analogues or simulators. The detection of a nerve agent analogue, pinacolyl methylphosphonate (PMP), has been demonstrated using an electrochemically, molecularly-imprinted polymer (MIP) polythiophene film set on a quartz crystal microbalance (QCM) transducer surface. " A nerve gas sensor for dimethyl methylphosphonate (DMMP) has also been based on chemically (p-phenylenediamine)-reduced graphene... 

The science of chemical sensors is being studied at Manchester University for the use and application of conducting polymers [4]. Derivatives of polyaniline, polythiophene, polypyrrole and poly(phenylene vinylene) doped with various ions have been investigated as chemical sensors for biosensors, volatile organic compounds, polymer field-effect gas-sensitive transistors and optical sensors based on electrochromic properties.
