Preparation of 3,4,9,10-Perylenetetracarboxylic Nanomaterial and Its Sensing Behavior
Organic nanomaterial PTTC was prepared by directly self-assembling in the gas phase with a thermal vacuum evaporation process. The product was characterized by scanning electron microscopy (SEM)
transmission electron microscopy (TEM)
infrared spectrum(IR)、fluorescence spectrum and differential thermal analysis(DTA). The PTTC nanomaterial can be solubilized in the solution of Tween 20
and L-lysine has strong sensitizing effect for the fluorescence of the dispersion system. A nano-fluorescent chemical sensor of L-lysine is built based on the above results. The linear range is 7.0010
-4
-5.4010
-7
mol/L with the detection limit of 8.3910
-8
mol/L. Further study show that the current difference of cyclic voltammogram of L-lysine is reduced by PTTC nanostructure
and it is expected to prepare a nano electrochemical sensor of L-lysine in the future.
