Abstract

Both redox forms of the dendrimer [dendr-64-NHCOCpFeII(eta 6-C6Me6)]64+/0, 6/7, are synthesized and characterized, and the 19-electron form reduces C60 to [dendr-64-NHCOCpFeII(eta 6-C6Me6)]64+(C60-.)64, 8.

Structural Diversity of Host–Guest and Intercalation Complexesof Fullerene C60

“…The organization of the potassium salt of a pentasubstituted fullerene into Ϸ17-nm spherical bilayer vesicles, [10] the assembling of fullerenes on surfaces, [11] the binding of porphyrins [12] and assembling of 64 C 60 -anions on the surface a dendrimer with terminal ferricinium moieties [13] are particular noteworthy. Dendrimers can also bind fullerenes within their internal cavities; [14] these include porphyrin-containing systems.…”

Dendrimers as Multielectron Storage Devices

“…6.2, has also been prepared. 23 Its electrochemical behavior is similar to that observed for the ferrocene-functionalized dendrimers: a single wave involving the exchange of 63 AE 6 electrons. Interestingly, the reduced form of this dendrimer, in which all the 64 peripheral units are present as 19-electron Fe(I) species, is capable to reduce fullerene molecule (C 60 ).…”

Quaternized and Thiazole‐Functionalized Free Radical‐Generating Organometallic Dendrimers as Antimicrobial Platform against Multidrug‐Resistant Microorganisms

“…This finding is exciting as it demonstrates for the first time that 18‐electron iron sandwich complexes spontaneously generate transient radicals. Indeed, their counterparts, the 19‐electron, and 17‐electron iron sandwich complexes are well‐known to form radicals, which account for their well‐exploited biological activity . Here, the mechanistic scenario leading to the formation of these radicals and their exact nature are yet to be understood and is a goal of a future study.…”
