摘要
探索先进的聚合策略，促进引入精细定制的供体-受体（D-A）结构，对于构建微孔聚酰亚胺（MPI）光催化剂至关重要。多米诺聚合允许多个反应在单一体系中进行，绕过了多酸酐单体在极性溶剂中的溶解度差，避免了低聚物的脱溶，规避了传统聚合的这些固有缺点。采用改进的溶剂热法，在0.5 h内即可制备出不同官能团的MPI家族。在空气中可见光照射下，含噻二唑基团的MPI光催化H2O2产率高达2177 μmol g-1 h - 1。该聚合策略为其他种类的多孔有机聚合物的合成展示了巨大的潜力，并促进了它们的应用前景。
Rapid Preparation of D-A Microporous Polyimides via Domino Polymerization for Photocatalytic Hydrogen Peroxide Production
The exploration of advanced polymerization strategies facilitating the introduction of delicate-tailored donor–acceptor (D-A) structure is crucial for the construction of microporous polyimide (MPI) photocatalysts. Domino polymerization allows multiple reactions to proceed in a single system, bypasses the poor solubility of multianhydride monomers in polar solvent, and avoids desolvation of oligomers, circumventing these inherent disadvantages of the conventional polycondensation. Thanks to the improved solvothermal process, the preparation of a family of MPIs embedded with different functional groups can be completed in 0.5 h. The obtained MPI containing thiadiazole group exhibits a high photocatalytic H2O2 production rate of 2177 μmol g–1 h–1 under visible light irradiation in air without sacrificial agents. The polymerization strategy demonstrates enormous potential for the synthesis of other kinds of porous organic polymers and promotes their promising applications.
期刊介绍：
ACS Macro Letters publishes research in all areas of contemporary soft matter science in which macromolecules play a key role, including nanotechnology, self-assembly, supramolecular chemistry, biomaterials, energy generation and storage, and renewable/sustainable materials. Submissions to ACS Macro Letters should justify clearly the rapid disclosure of the key elements of the study. The scope of the journal includes high-impact research of broad interest in all areas of polymer science and engineering, including cross-disciplinary research that interfaces with polymer science.
With the launch of ACS Macro Letters, all Communications that were formerly published in Macromolecules and Biomacromolecules will be published as Letters in ACS Macro Letters.
