Fast detection of nitroaromatics using phosphonate pyrene motifs as dual chemosensors

A new class of dual fluorescent chemosensors for nitroaromatic compounds (NACs) based on phosphonated pyrene derivatives is reported, showing high selectivity towards trinitrotoluene (TNT). The strong intermolecular interactions (π-π stacking and hydrogen bonding) allow high fluorescence quenching w...

Zusammenfassung:A new class of dual fluorescent chemosensors for nitroaromatic compounds (NACs) based on phosphonated pyrene derivatives is reported, showing high selectivity towards trinitrotoluene (TNT). The strong intermolecular interactions (π-π stacking and hydrogen bonding) allow high fluorescence quenching with visual detection in short response times.
