研究目的
Investigating the design and synthesis of a cross-linked conjugated polymer photosensitizer (CPTF) for efficient sunlight-induced photooxidation in organic synthesis, bacterial killing, and organic waste treatment.
研究成果
The cross-linked porous conjugated polymer photosensitizer CPTF was successfully designed and synthesized, demonstrating high 1O2 generation efficiency, excellent photostability, and large specific surface area for photooxidation under sunlight. CPTF showed excellent recyclability and was effective in sunlight-induced organic synthesis and wastewater treatment, indicating its potential for green chemistry applications.
研究不足
The study does not address the potential environmental impact of the synthesized CPTF or its degradation products. Additionally, the scalability of the synthesis process and the cost-effectiveness of CPTF for large-scale applications are not discussed.
1：Experimental Design and Method Selection:
The study involved the design and synthesis of CPTF through a three-step process, starting with the selection of DTF as a model compound, followed by the design of a conjugated polymer PTF, and finally the cross-linked porous conjugated polymer CPTF. The methodology included Suzuki coupling polymerization and characterization by NMR spectra, UV-vis diffuse reflectance spectra, and Brunauer?Emmet?Teller (BET) surface area measurements.
2：Sample Selection and Data Sources:
The study used benzaldehyde as a model compound for photooxidation reactions, and Rhodamine 6G and staphylococcus aureus (S. aureus) for wastewater treatment applications.
3：List of Experimental Equipment and Materials:
The synthesis involved TPA-2B and FN-2Br monomers, and characterization techniques included NMR, UV-vis spectroscopy, and SEM.
4：Experimental Procedures and Operational Workflow:
The photooxidation of benzaldehyde was performed under simulated AM
5：5G irradiation, and the photocatalytic activity was tested in solvent-free conditions and scaled up. The wastewater treatment application involved the decomposition of Rhodamine 6G and bacterial killing under simulated AM5G irradiation. Data Analysis Methods:
The study analyzed the 1O2 generation efficiency using ABDA as an indicator, and the photostability was tested by comparing the relative 1O2 generation efficiencies under AM1.5G irradiation for different times.
