“…This is a broad and rapidly expanding subject, which has already been thoroughly reviewed in the recent literature. [10][11][12][13][14] This review is therefore going to concentrate on the significant achievements within the area of internally functionalised dendrimer catalysts. Rather than describe the achievements chronologically, similar topics are grouped together for clarity.…”

Catalysis inside dendrimers

2002

Catalytic sites can be placed at the core, at interior positions or at the periphery of a dendrimer. There are many examples of the use of peripherally functionalized dendrimers in catalysis and this subject has been thoroughly reviewed in the recent literature. This review is concerned only with dendrimer based catalysis involving catalytic sites at the core of a dendrimer and within the interior voids. In covering the significant achievements in this area, we have concentrated on examples that highlight key features with respect to positive and/or negative catalytic activity.

“…In recent years, metallodendritic chemistry − has emerged as one of the most interesting topics within suprasupermolecular chemistry − due to the inherent novel physical properties. This has facilitated studies in sensor arrays, optical, redox, electrochemical, − and photochemical characteristics ,− as well as biological diagnostic , and catalytic attributes. − Such metallodendrimers generally incorporate metal ions into their infrastructure via use as cores, branching centers, arm connectors, and termini or by metal incorporation at specific loci within the preassembled dendritic framework. In our previous work, − the bis(2,2‘;6‘,2‘ ‘-terpyridine)ruthenium(II) complex (i.e., [−<Ru>−]) has been employed as a building block connector and has afforded entrance to numerous metallodendritic assemblies, all utilizing external counterions, such as Cl - , BF 4 - , and PF 6 - .…”

Synthesis of Neutral Metallodendrimers Possessing Adamantane Termini: Supramolecular Assembly with β-Cyclodextrin

et al. 2004

First and second generations of 1 → (2 + 1) C-branched metallodendrimers were prepared employing terpyridine−RuII−terpyridine connectivity. Each surface dendron is comprised of a terpyridinyl (focal group), a diester (capable of easy hydrolysis), and a terminal adamantyl moiety (for encapsulation). Internal incorporation of counterbalancing carboxylate moieties derived by ester cleavage with formic acid and subsequent treatment of the intermediate diacid with base gave access to overall charge−neutral dendritic macromolecules. Aqueous solubility was effected by the supramolecular encapsulation of the terminal adamantane moieties with β-cyclodextrin, causing dissolution of the water-insoluble dendrimers (11 and 15) into an aqueous environment.
