The nano-supramolecular cascade reactor based on sulfobutylether-β-cyclodextrin, not only displayed glucose-activated radical polymerization to form hydrogel in situ, but also produced hydroxyl radicals for drug-resistant bacteria elimination and wound protection, which successfully achieved diabetic wound healing and in situ therapy.
<正>Molecular nanotubes are nanoscale organic materials with tubular architecture, that show potential applications in molecular recognition/separation, cross-membrane transportation, catalysis in confined spaces, and nanoelectronics [1]. However, the precise construction of molecular nanotubes with well-defined cavity sizes and shapes is non-trivial. 相似文献
It remains a significant challenge to construct an integrated catalyst that combines advantages of homogeneous and heterogeneous catalysis with clarified mechanism and high performance. Here we show atomically precise CuAg cluster catalysts for CO2 capture and utilization, where two functional units are combined into the clusters: metal and ligand. Due to atomic resolution on total and local structures of such catalysts to be achieved, which disentangles heterogeneous imprecise systems and permits tracing the reaction processes via experiments coupled with theory, site-specific catalysis induced by metal-ligand synergy can be accurately elucidated. The CuAg cluster catalysts exhibit excellent reactivity and recyclability to forge the C−N bonding from CO2 formylation with secondary amines that can make the cluster catalysts more unique compared with typically homogeneous complexes. 相似文献
Sun's group from Beijing University of Technology, China, prepared red-emission CDs in high yield by a solvent-free method based on o-phenylenediamine and analyzed the origin of the red emission and the formation of CDs. 5,14-Dihydroquinoxalino[2,3-b]phenazine (DHQP) was successfully isolated from the system and identified as the fluorophore of the CDs. These findings provide insight into the PL mechanism of this type of CDs and may guide the further development of CDs that can be tuned to obtain tailored properties.
Tu group from Fudan University utilized a supramolecular assembly strategy and employed terpyridine Zn(II) complexes to selectively improve fluorescent properties and enhance the ability to bind components in latent fingerprints (LFPs), which provides an efficient approach for practical LFPs recording and analysis in different scenarios.
