The invention provides a two-dimensional coordination polymer synthesized based on a structure inducer. The X-ray powder diffraction peaks of the coordination polymer are as follows: 10.06 (+0.5), 11.85 (+0.5), 26.55 (+0.5), 27.97 (+0.5), 36.12 (+0.5), and the angle range of 2theta is between 5 60. The two-dimensional coordination polymer is synthesized based on a structure inducer, and a novel two-dimensional coordination polymer is constructed by using amphoteric pyridinium salt oxygen anion as the structure inducer and copper ion as the coordination agent with benzotetracarboxylic acid. Two-dimensional coordination polymer film was obtained by ultrasonic peeling; this two-dimensional polymer film has molecular screening performance and can selectively screen Rhodamine B; it can be used to separate and purify special dyes and organic compounds in water body; compared with photolysis of organic dyes in water body, molecular screening method is more efficient, and can avoid secondary pollution caused by decomposition of organic dyes, at the same time, it can also purify water body. The material is cheap and easy to obtain, and the reaction conditions are mild, which is conducive to industrial production.
