Summary: | The invention discloses a near-infrared siloxane-based quinoline polymer, a preparation method thereof and application of the near-infrared siloxane-based quinoline polymer in detection of copper ions, and belongs to the field of preparation of high-molecular fluorescent substances. 4-diphenylaminobenzaldehyde, tetramethyl divinyl disiloxane and 4, 4-diaminodiphenyl formamide are adopted as raw materials, a quinoline group is introduced through a Povarov Reaction reaction, and the siloxane-based quinoline polymer with the structure shown in the formula I is prepared. The invention is applied to the aspect of copper ion detection, and provides a fluorescent probe which has the advantages of high-sensitivity and high-stability detection of copper ions and multi-site recognition of copper ions aiming at the problem of lack of polymer fluorescent probes for multi-site detection of copper ions and excellent biocompatibility. The invention further discloses a preparation method of the siloxane-based quinoline polym |
