Abstract

The invention belongs to the field of a functional high molecular material, and particularly relates to a series of side chain type electroactive fluorescent polymers, a preparation method and use for detecting an oxidizing or reducing substance. Fluorescence detection of the oxidizing or reducing substance is realized by utilizing the characteristic that the fluorescence intensity of the electroactive fluorescent polymer reversibly changes along with an oxidation reduction state of an aniline chain segment. The preparation method comprises the following steps of: synthesizing the fluorescentpolymer containing the aniline chain segment and a fluorescent group on a side chain through a ternary polymerization method; after preparing polymer into solution, keeping the aniline chain segment in the polymer in a reducing state or intermediate oxidizing state by using a chemical oxidation reduction method or electrochemical method; and then testing a fluorescence response situation of the aniline chain segment to the oxidizing or reducing substance by using a fluorescent spectrometer. The detection method has the advantages of wide variety of detection objects, high stability, low detection lower limit, reusability and the like, and has extremely broad application prospect in the fields of biology, chemistry, foods, environment and the like.

Description

technical field

[0001] The invention belongs to the field of functional polymer materials, and specifically relates to a series of side chain type electroactive fluorescent polymers, a preparation method and a method for detecting oxidized or reduced substances. technical background

[0002] Since the 1990s, the synthesis and properties of organic polymer light-emitting materials have aroused the interest of many researchers, and have been widely used in the research of photoelectric conversion and electroluminescence. At the same time, with the rapid development of supramolecular chemistry and coordination chemistry, the study of designing new sensors using fluorescent functional polymers to realize molecular / ion recognition has attracted extensive attention.

[0003] The research work of traditional polymer fluorescent sensors is mostly designed based on the principle of host-guest interaction, and the detection objects are mainly ions in solution, biological macromolecule...
