Design, synthesis of nitrogen-rich triazine derivatives and its
application in water sample, Vegetables and Oil Product
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.
