ABSTRACT:
The invention relates to the use of molecular tweezers as sensitive materials in chemical sensors intended to detect or assay organic compounds in the vapour state, and in particular nitro compounds.These molecular tweezers correspond to the general formula (I):in which:MC1and MC2represent macrocycles;p and q are equal to 0 or 1;X and Y are optionally substituted C1to C10alkylene groups; whileE represents an optionally substituted cyclic or heterocyclic spacer group;and in which MC1and MC2are positioned facing each other.Fields of application: detection of explosives, control and monitoring of atmospheric pollution and of the quality of ambient air in relatively confined spaces, and monitoring of industrial sites.
