Embodiment 1

[0085] 1. Preparation of BFPB

[0086] The temperature of the system was kept at 70° C., and under nitrogen protection, a solution of 4-hydroxybenzaldehyde (1.259 g, 10.3 mmol) dissolved in 15 mL of anhydrous DMF was added to a 100 mL round-bottomed flask equipped with a stirring bar and a condenser, and potassium carbonate ( 4.275g, 30.9mmol) was treated for 1 hour. Pentaerythritol tetrabromide (1 g, 2.58 mmol) dissolved in 5 mL of anhydrous DMF was then slowly added to the system, and the reaction mixture was heated at 100° C. for 72 hours with vigorous stirring. After cooling to room temperature, most of the solvent was removed by filtration under reduced pressure. Add ice water, use CH 2 Cl 2 extraction, the organic phase was washed repeatedly with ice water, and then with anhydrous MgSO 4 After drying, the solvent was removed to obtain 1.4 g of BFPB with a yield of 95%.

Abstract

The invention belongs to the technical field of antibacterial nano materials, and particularly relates to a polymer, a preparation method thereof, and application of the polymer as a bacterium detection and antibacterial material. At present, the antibacterial nano material becomes a research hotspot in the antibacterial field due to the advantages of stability, difficulty in generating drug resistance and the like. According to the ferriporphyrin-based porous organic metal polymer provided by the invention, pyrrole and a compound BFPB are used as raw materials, so that the polymer is synthesized by a hydrothermal method, and the preparation method is simple. The polymer has good chemical and thermal stability, the 3D interconnected porous structure provides rich catalytic active sites, and the polymer has good peroxidase-like activity. Under a near-infrared illumination condition, the polymer has a killing effect on staphylococcus aureus, and the Ab2@Au@FePPOPBFPB prepared from the polymer has good specificity and sensitivity when being applied to detection of staphylococcus aureus.

Description

technical field [0001] The disclosure belongs to the technical field of porous organic polymers, and in particular relates to a porous organic polymer based on iron porphyrin, a preparation method of the polymer, and an application of the polymer as a detection bacteria and antibacterial material. Background technique [0002] The information disclosed in this Background section is only intended to increase the understanding of the general background of the disclosure, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes prior art that is already known to those skilled in the art. [0003] Bacterial infection is one of the major threats to human health and is the leading cause of death in many developing and underdeveloped populations. The development of nanomaterial technology provides opportunities for the development of new antibacterial drugs. Compared with traditional antibiotics, nanomaterials are less likel...
