Photocatalysis based on chromophores such as porphyrin, coumarin, anthraquinone, and pyrene is a promising technology to achieve green synthesis of various high-value chemicals, but the robust non-covalent immobilization onto light-inert scaffolds for industrialization-oriented heterogeneous photocatalysis remains challenging. In this work, simple universal strategy presented preparing highly efficient recyclable photocatalysts from chromophores, which achieved via biotinylation chromophore molecules subsequent supramolecular binding chromophore-biotin dyads streptavidin-decorated magnetic beads. As an example, commercial beads modified by 5,10,15,20-tetrakis(4-aminophenyl) porphyrin not only possessed remarkable photocatalytic activities oxidative coupling benzylamine derivatives oxidation thioanisole with highest product yields beyond 95% turnover numbers approaching 10000, driven photogenerated reactive oxygen species also demonstrated impressive chemical stability recyclability separation during 10 successive test cycles. The findings revealed in work pave way advancing valuable organic compounds pharmaceutical industry, agricultural sector, etc., rationally designed systems.

Covalent organic frameworks (COFs) serve as an outstanding platform for heterogeneous photocatalysis. We synthesized two analogous pyrene-based two-dimensional COFs with π-conjugated networks, one linked by C═N bonds and the other C═C bonds, through Schiff base Knoevenagel condensation reactions, respectively. investigated impact of these linkages on photocatalytic activity COFs, using visible-light-mediated thioesterification a model reaction. It was found that olefin-linkage COF outperformed imine-linkage photocatalyst. The developed protocol demonstrated broad substrate scope, including 35 diverse carboxylic acids, 14 drug molecules, several disulfide coupling partners, achieving up to 95% yield thioesters. practical utility this strategy is further its successful application in gram-scale reactions. photocatalyst robust successfully reused multiple cycles without any loss catalytic activity. backbone facilitated enhanced electron transfer upon light irradiation, enabling cross-coupling acid reductive cycle.

The special pathological microenvironment of infected wounds (pathology weakly acidic, hypoxic, and overexpressed H2O2) provides fertile soil for the development disease. Tailoring treatment based on specific characteristics infectious (IME) has emerged as a novel direction in antimicrobial therapies. Here, polyoxovanadate (POV)-based covalent organic polymer (POV-Fc-COP) with inherent photothermal activity was facilely prepared via copolymerization 1,1′-bi(3-dimethylamino-1-oxo-2-enyl-ferrocene) (BDOEF) tris-NH2-modified POV (tris-V6O9), which nanovanadium oxide (V2O3 V2O5) core shell were generated directly during Michael addition–elimination reaction. unique structure composition impart pH-responsive peroxidase-like (POD-like) catalase-like (CAT-like) activities, concurrently, to POV-Fc-COP. Specifically, acid-activated mimicking-POD could consume H2O2 microenvironment, producing toxic •OH combat bacteria biofilms. vanadium consumes excessive acid, resulting an increase pH. Meanwhile, CAT-like transform excess expression into O2 relieve hypoxia induced by damage blood vessels facilitate wound healing. Additionally, synergistic amplified therapeutic effect triggered application laser irradiation facilitates rapid eradication biofilm, minimizing detrimental impacts bacterial proliferation IME, thereby accelerating restoration IME return normal state. Therefore, POV-Fc-COP dual-enzyme functionality not only utilize but also regulate significantly expediting healing bacteria-infected wounds. This study demonstrates simple method preparation intelligent platform programmed antibacterial antibiofilm formation, thus promoting while utilizing improving IME.
