A new dibenzothiophene-based dual-channel chemosensor for cyanide with aggregation induced emission

Based on dibenzothiophene fluorophore, a new colorimetric and fluorescent sensing material 2-(dibenzothiophenyl-4-ethenylidenyl)-1,3-indanedione (DTI) was developed, which was a favorable turn-off fluorescent sensor of monitoring CN– ion at extremely low detection limit (0.14 μM) in 99 % aq. DMSO solution. The response mechanism of DTI towards CN– could put down to nucleophilic attack of cyanide group (CN–) toward the double-bond between the dibenzothiophene and the 1,3-indanedione units, which breaking intramolecular charge transfer (ICT) process. This mechanism was proposed by 1H NMR, Job's titration and DFT calculation, leading to a significant fluorescence attenuation and a visual color change. The absorption and emission experiments demonstrated that it showed highly sensitive, selective and good stability for CN– in DMSO/H2O (1:99, v/v). Moreover, DTI displayed high effectiveness in monitoring the CN– in test strips achieved to conveniently determinate CN– by naked-eye without any instruments.
