[资源] Nature Commun.--Metallodendrimers and stabilizationof size-selected AuNPs

最新出版的Nature communication刊发了由著名金属有机化学家、法国科学院院士、波尔多大学化学系Didier Astruc教授课题组撰写的文章--Metallodendrimers in three oxidation states withelectronically interacting metals and stabilizationof size-selected gold nanoparticles”,发来与虫友赏析,希望对大家有所帮助并希望与做dendrimer和polymer与纳米金的虫友探讨,话不多说,直接上Abstract(附件论文):

评述:Metallodendrimers containing redox-robust centres are functional molecules with many potential applications. Here, the authors fabricate iron containing metallodendrimers in a range of oxidation states and investigate their interactions with, and stabilization of, gold nanoparticles.

Abstract:
Metallodendrimers containing redox-robust centres might show applications in molecular redox recognition, sensing, biosensing and catalysis. So far, however, no metallodendrimer is known in several oxidation states. Here we report metallodendrimers with two electronically communicating iron centres that are stable and isolated in both the FeII and FeIII oxidation states, and in addition as class-II mixed-valent FeIIFeIII complexes. These dendrons are branched to arene-centred dendrimer cores either by Sonogashira coupling or ‘click’ reactions. The latter reaction involves the introduction of intradendritic 1,2,3-triazolyl ligands, which allows investigation of the selective role of these ligands in intradendritic AuIII coordination and Au0 nanoparticle stabilization. As a result, and using the various metallodendrimers with different oxidation states, small Au0 nanoparticles are intradendritically stabilized by the triazole ligands, whereas with the related non-‘click’ dendrimers large Au0 nanoparticles are formed outside the dendrimers and stabilized by a group of dendrimers.
