“…We developed direct polymerization of Y5-TA monomer and PO-N in a spin-coated blend film by heating at 130°C for 30 min. [39][40][41] The UV-vis absorption spectra of the films are compared in Figure S6, Supporting Information. The spectrum of the pristine Y5-TA film shows a sharp absorption over the nearinfrared range, similar to the spectrum of the Y5 acceptor.…”

Recyclable conjugated polymers are important for realizing eco‐friendly electronics with advantages of solution processability and flexibility. A recyclable conjugated polymer, PY‐TIP is developed, of which a key monomer is successfully extracted via a mild depolymerization process and is reused for the synthesis of novel conjugated polymers. One‐shot preparation of polymer acceptor and its bulk‐heterojunction (BHJ) is demonstrated from the recycled monomer, Y5‐TA, for the first time and the resulting BHJ film shows optimal nanoscale morphology for efficient charge generation and transport. As a result, the solar cells prepared using the BHJ film show a higher efficiency of 13.08% and much improved thermal and mechanical stability compared with those based on the small molecular acceptor. These results are important in that the various polymers can be prepared from the recycled monomer in a solid state without organic solvents and purification step and this strategy is effective for improving the thermal and mechanical stability of the BHJ film as well as achieving high photovoltaic performance. PY‐TIP is exemplary in that it can reproduce its monomer which can be used to synthesize conjugated polymers with novel chemical structures and physical properties. This work provides a design guideline for developing recyclable conjugated polymers with dynamic covalent bonds.

The treatment of infected wounds remains a challenging biomedical problem because of the complex microenvironment at the wound bed. Some natural bioactive small‐molecule hydrogelators with unique rigid structures can self‐assemble into supramolecular hydrogels, serving as supporting dressings and therapeutic agents for wound healing. However, they are still suffered from low structural stability and bio‐functionality. Herein, we proposed a supramolecular hydrogel antibacterial dressing with a dual nanofibrillar network structure. A nanofibrillar network created by small‐molecule hydrogelator, puerarin extracted from the traditional Chinese medicine Pueraria, was interconnected with a secondary macromolecular silk fibroin nanofibrillar network induced by Ga ions via charge‐induced supramolecular self‐assembly. The resulting hydrogel features adequate mechanical strength for sustainable retention at wounds. The good biocompatibility and efficient bacterial inhibition were also obtained when the Ga ion concentration was 0.05%. Otherwise, the substantial release of Ga ions and puerarin endows the hydrogel with excellent hemostatic and antioxidative properties. In vivo evaluation on a mouse infected wound model demonstrates that its healing effect outperformed that of a commercially available silver‐containing wound dressing. The experimental group successfully achieved a 100% wound closure rate on day 10 of treatment. This study sheds a new light on the design of nanofibrillar hydrogels based on supramolecular self‐assembly of naturally derived bioactive and/or biofunctional molecules as well as their clinical use for the treatment of chronic infected wounds.This article is protected by copyright.
