Study of fluorescent piconjugated materials used as nitroaromatics chemosensors

Résumé

To be able to detect explosives ultra-traces has become a societal need particularly to anticipate terrorist attacks. During the last decade, despite wellstudied heavy analytical techniques, more sensitive and portable new gas-chemosensors have been developed. The sensor principle is based on a sensitive material interacting with the gaseous analyte. These interactions can induce a variation of the intrinsic properties of the material. For example, it can be fluorescence quenching easily identified with a spectrofluorimeter. In this paper, several organic materials have been identified as promising fluorescent explosives sensors and especially as nitroaromatic sensors. These sensors materials are polymers which backbone is a regularly alternated linking of π-conjugated segments (called fluorophores) and chiral units
