In the chemical sensor in order it detects or to analyze the organicity chemical compound of steam state, or, at least use of the chemical compound of 1 where it corresponds to

摘要

The present invention relates to the use of molecular tweezers as sensitive material in a chemical sensor for the purpose of the organic compounds in the vapor state, to analyze or detect the nitro compounds. Molecular tweezers these correspond the following general formula (I). [Formula 1] In the formula, MC ₂ and MC ₁ represents a macro ring; p and q is equal to 0 or 1; The Y and X, is an alkylene radical _{C 10} from _{C 1} may even be substituted; E represents a heterocyclic spacer group or cyclic which may be substituted; MC ₂ and MC _1, and are arranged facing each other. ] Monitoring of industrial site monitoring and detection of explosives, and control of the ambient air quality and air pollution in space that has been relatively limited: the field of application.
