The invention relates to the use of at least one polymer comprising a repeating unit of formula (I): n nin which:n X and Y=single bond or linear C 1 -C 50 hydrocarbon group; R 1 and R 2 =H, CN, C(Z) 3 , CH(Z) 2 , CH 2 Z with Z=halogen; NH 2 , NHR 3 , NR 3 R 4 with R 3 , R 4 =halogen, CH 3 or linear or branched, saturated or unsaturated C 2 -C 20 hydrocarbon chain, optionally comprising one or more heteroatoms and/or chemical functions comprising at least one heteroatom; at least one from among R 1 and R 2 being ≠H;n nor of a composite comprising this polymer and one or more conductive charges, as sensitive material in a sensor for detecting nitro compounds.n n Applications: Detection of explosives, control/monitoring of atmospheric pollution and of ambient air quality, monitoring of industrial sites. |
