Poly(3‐alkoxyphenylthiophenes) For VOCs Detection

In this work, poly(3‐(4‐octyloxyphenyl)thiophene has been synthetized by an oxidative coupling polymerization reaction and employed in a chemiresistor structure to probe its potential as VOCs sensor. The devices has been exposed to toluene, acetone and ethanol vapours. The chemiresistor has exhibited fast response time (<1 min), good stability over more than two weeks under ambient conditions and good sensitivity to VOCs, demonstrating to be a viable option for detection of VOCs.
