Abstract

A triazine nitrogen-rich derivative fluorescent probe, 1,1’-(6-chloro-1,3,5-triazine-2,4-diyl)bis(1H-benzo[d][1,2,3]triazole)(L), has been synthesized and successfully achieved for the efficient detection for Fe3+, Cr2O72-, nitrobenzene as a turn-off chemosensor in DMF/H2O. The quenching constant(Ksv) and detection of limit for Fe3+, Cr2O72-, nitrobenzene on fluorescence response of the sensor can be as low as 470.00 M-1, 359.94 M-1, 3.62*103 mL-1, 2.10*10-5 M, 5.73*10-5 M, 1.24*10-5 mL, respectively. On the contrary, It is applied to detected for toluene and xylene as a turn-on chemosensor in DMF. The quenching constant and detection of limit for toluene and xylene on fluorescence response of the sensor can be as low as -11.05 mL-1, -6.23 mL-1, 9.30*10-4 mL, 7.35*10-3 mL, respectively. The application of water sample and vegetables showed that the L had high sensitive detection for Fe3+ ions. Meanwhile the application of gasoline, diesel and engine oil showed that the L had high sensitive detection for toluene and xylene.
