The paper was functionalized with thiol groups through a reaction with thioglycolic acid, which served a dual purpose: partially reducing Cu(II) to Cu(I) and stabilizing active copper species via Cu–S interactions. Spectroscopic analysis confirmed the formation of highly dispersed multi-valent Cu2O/CuO on the thiol-functionalized cellulose, resulting in a highly efficient copper catalyst. This catalyst demonstrated excellent performance in the oxidative coupling of various amines to imines, achieving yields of 39–99% within 10–30 min. A key advantage of this system is its reusability; the catalyst maintained remarkable stability and activity over ten reaction cycles with straightforward recovery. This paper-based catalyst offers a promising strategy for eco-friendly and cost-effective synthetic processes, with significant implications for green chemistry and industrial applications."}],"extern":"1","publication":"Scientific Reports","issue":"1","citation":{"bibtex":"@article{Sangkaworn_Limprasart_Höfler_Gutmann_Pornsuwan_Bunchuay_Tantirungrotechai_2025, title={Copper-supported thiol-functionalized cellulose as a paper-based catalyst for imine synthesis}, volume={15}, DOI={10.1038/s41598-025-95144-1}, number={1}, journal={Scientific Reports}, author={Sangkaworn, Jariyaporn and Limprasart, Waranya and Höfler, Mark Valentin and Gutmann, Torsten and Pornsuwan, Soraya and Bunchuay, Thanthapatra and Tantirungrotechai, Jonggol}, year={2025}, pages={9893} }","short":"J.

The main problem is that direct measurement, from both quantitative and qualitative point of view is challenging. While there are methods to assess solution strength and wettability of ionic liquids with cellulose materials, the main challenge lies in the combination of a solid substrate and an applied liquid, limiting the number of accessible methods. We demonstrate in this paper that an in-situ solid-state NMR spectroscopical approach is capable of monitoring in real-time the mobility of ionic liquids in cellulose-based substrates. Specifically, we employ 1H → 13C cross polarization magic angle spinning (CP MAS) NMR spectroscopy to examine mobility changes over varying exposure times in paper samples treated with ionic liquids. Through this approach, we capture the temporal evolution of IL signals, which in turn provide insights into mobility changes of ILs and also allow for identifying changes in cellulose crystallinity. The approach allows for a simple, semiquantitative assessment of cellulose solubility in ionic liquids and is in principle applicable to other biomass materials as well.","lang":"eng"}]},{"date_created":"2026-02-07T15:47:03Z","type":"journal_article","issue":"80","publication":"Chemical Communications","extern":"1","abstract":[{"text":"Herein, we report a solid-state polycyclotrimerization of 1,4-diethynylbenzene using mechanochemical activation in a ball mill, yielding a highly porous and hydrophobic hyperbranched polymer (HBP) with a specific surface area of up to 570 m2 g−1. The reaction, catalyzed by Fe(hmds)2 and conducted under solvent-free conditions, was optimized by varying milling time and frequency. This method enables the efficient synthesis of insoluble, porous organic polymers with high yields (up to 95%) and offers an environmentally friendly alternative to traditional solution-based polymerizations.","lang":"eng"}],"language":[{"iso":"eng"}],"doi":"10.1039/D5CC04700E","author":[{"last_name":"Hutsch","first_name":"Stefanie","full_name":"Hutsch, Stefanie"},{"full_name":"Grätz, Sven","last_name":"Grätz","first_name":"Sven"},{"last_name":"Lins","first_name":"Jonas","full_name":"Lins, Jonas"},{"id":"118165","full_name":"Gutmann, Torsten","last_name":"Gutmann","first_name":"Torsten"},{"last_name":"Borchardt","first_name":"Lars","full_name":"Borchardt, Lars"}],"publication_identifier":{"issn":["1359-7345"]},"year":"2025","title":"Solid-state polycyclotrimerization of diynes to porous organic polymers","intvolume":" 61","date_updated":"2026-02-17T16:16:36Z","citation":{"mla":"Hutsch, Stefanie, et al. “Solid-State Polycyclotrimerization of Diynes to Porous Organic Polymers.” Chemical Communications, vol. 61, no. 80, The Royal Society of Chemistry, 2025, pp. 15622–15625, doi:10.1039/D5CC04700E.","bibtex":"@article{Hutsch_Grätz_Lins_Gutmann_Borchardt_2025, title={Solid-state polycyclotrimerization of diynes to porous organic polymers}, volume={61}, DOI={10.1039/D5CC04700E}, number={80}, journal={Chemical Communications}, publisher={The Royal Society of Chemistry}, author={Hutsch, Stefanie and Grätz, Sven and Lins, Jonas and Gutmann, Torsten and Borchardt, Lars}, year={2025}, pages={15622–15625} }","ama":"Hutsch S, Grätz S, Lins J, Gutmann T, Borchardt L.

The formation of dendrites as well as the decay of a secondary metallic sodium species is observed, and local structures are analyzed up to the point of capacity degradation and cell failure.
