Abstract

The properties of a series of sexithiophenes bearing amide or ester functionalities in the α,ω-positions are reported. Isolation of the ester functionalities from the sexithiophene core by an ethylene spacer led to a device with moderate hole mobilities (1.2.10^-2 cm²V ^-1s^-1) and on/off ratios (10³). A bottom contact device based on this sexithiophene showed a good response to a 5 ppm NO atmosphere, encouraging future studies on gas sensing OTFT based on these polar-functional ised OTFT.
