Abstract

The invention discloses application of a diketopyrrolopyrrole derivative. The diketopyrrolopyrrole derivative has a selective complexation effect on Hg<2+>, can easily realize decomplexation and is applicable as an Hg<2+> recognition substance to preparation of a fluorescent sensor used for detecting Hg<2+> in an aqueous solution. The prepared fluorescent sensor used for detecting Hg<2+> has the characteristics of recognizability with naked eyes, high sensitivity and repeated usability, has high Hg<2+> selectivity and is free of interference by cations like Ag<+>, Pb<2+>, Cu<2+>, Cr<3+>, Mn<2+>, Fe<3+>, Co<2+>, Ni<2+>, Zn<2+>, Cd<2+> and Al<3+> in detection of Hg<2+>. The fluorescent sensor is widely applicable to the fields of environmental engineering, biological detection, etc.

Description

technical field

[0001] The present invention relates to a class of diketopyrrolopyrrole derivatives in Hg 2+ The application in detection belongs to the field of functional materials. Background technique

[0002] Developed industry has brought great wealth to human beings, but it has also brought serious environmental hazards of heavy metals. Among them, mercury pollution has become a major global environmental problem. my country is a large country in the production, use and emission of mercury, and the situation of mercury pollution prevention and control is very severe. Today's mature mercury detection technology mostly relies on large-scale analytical instruments, but sample preparation takes a long time and the detection cost is expensive, which cannot meet the current needs of large quantities, convenience, and speed, and chemical sensors can better meet the above requirements.

[0003] Diketopyrrolopyrrole (DPP) functional dyes have a high fluorescence quantum yiel...
