In this paper, three styrene acrylic derivative was synthesized, its through the mechanical force grinding, fluorescent substances from violet to green and yellow.Fluorescent efficiency also corresponding changes have taken place, and the use of ethanol and n-hexane and, under the condition of material color again from yellowish green to violet.Show that the compound has piezochromic nature and of reversibility.When the concentration of THF was 0%, almost no fluorescent compounds TPETPAN.But when the water volume fraction increased, the fluorescence intensity increased, and when the concentration of 90% water, fluorescence effect is strongest.And through XRD test, we found that the accumulation of the material model and molecular conformation change, make its produce different fluorescence, and pressure cause discoloration property has the very good reversibility. |
