This compound appears as a yellow block with a melting point: 76-78 deg.C, molecular formula C 11 H 9 N 3 S, the chemical name is: 2- ((E) - (((E) -benzylidene) hydrazono) methyl) thiazole; the structure of the compound is detailed in the specification, and the compound has certain fluorescence property and anticancer activity.)

1. A compound which is yellow blocky crystal in appearance and has a melting point of: 76-78 deg.C, molecular formula C₁₁H₉N₃S, the chemical name is: 2- ((E) - (((E) -benzylidene) hydrazono) methyl) thiazole, having the structure:

the material crystal belongs to an orthorhombic system, the space group is Pbca, Z＝8。

2. a method of synthesizing a compound as claimed in claim 1, characterized in that: taking (E) -2- (hydrazono) thiazole and benzaldehyde as raw materials, reacting at normal temperature or heating to reflux, and reacting in organic solvents such as methanol/ethanol/acetonitrile/dichloromethane/chloroform/tetrahydrofuran/acetone, and the like, wherein the steps are as follows:

1) dissolving (E) -2- (hydrazono) thiazole in an organic solvent, adding benzaldehyde according to the mass ratio of 1:4-4:1, and stirring or grinding at a certain temperature for 1-10 h to complete the reaction; if a solid phase reaction is adopted, an organic solvent can be omitted;

2) filtering, and naturally volatilizing the filtrate to separate out orange blocky crystals which are target products; if solid phase reaction is adopted, the target product crystal can be obtained by recrystallization with organic solvents such as methanol/ethanol/acetonitrile/dichloromethane/chloroform/tetrahydrofuran/acetone and the like.
