The invention discloses a water-soluble perylene bisimide compound and an application of a water-soluble perylene bisimide compound for preparing DNA intercalators, inhibiting cancer cell growth and resisting tumors, belonging to the technical field of biological drug chemical synthesis. A cationic amino functional group is introduced into perylene derivatives and single perylene systems, so that the water solubility is greatly improved, the amino functional group is bound to light stability of perylene derivatives, and a series of novel water-soluble perylene bisimide compounds are obtained. The synthetic compound can be effectively embedded into DNA double helix base pairs of the cell nucleus and can serve as a DNA intercalator. The synthetic compound has a planar rigid structure, can be specifically enriched on a fixed tissue cell nucleus, is high in fluorescence intensity and easy in fluorescence imaging and can be compared favorably with commercial cell nucleus dyes DAPI. The synthetic compound can effectively inhibit growth of cancer cells such as U2OS, HCT116, HeLa and AGS, has an obvious antitumor effect and can be applied to preparing antitumor drugs.

The present invention relates to a preparation method of amorphous ZnO / AgCl composite visible light photocatalyst, comprising the following steps: 1) using AgNO 3 The AgCl powder generated by the reaction between the solution and the KCl solution is the raw material of the photocatalyst; 2) dissolve zinc nitrate in deionized water to form a uniform solution; dissolve urea in deionized water to form a uniform solution; 3) take the AgCl powder and add it to the zinc nitrate and urea solution; soak and stir; 4) after the product is filtered and washed with deionized water, add methyl orange solution, and irradiate under visible light; 5) filter the precipitate obtained in step 4), wash with deionized water, and vacuum After drying, an amorphous ZnO modified AgCl composite high-efficiency visible light photocatalyst is obtained.
