Click assemblies and redox properties of arene- and gold-nanoparticle-cored triazolylbiferrocene-terminated dendrimers

Large dendritic assemblies terminated by organometallic groups that possess a rich redox chemistry and stability in two or more oxidation states are highly desired as electron-reservoir systems, sensors, and redox catalysts. Here the synthesis and click (CuAAC) chemistry of ethynyl biferrocene including branching onto dendrons, arene-cored dendrimers, and gold nanoparticles are developed, and the role of the 1,2,3-triazole linkers and redox chemistry of these assemblies are discussed including the properties and stabilities of the redox states.

Ferrocenyl dendronized polymers

Styrenic dendrons functionalized with ferrocenyl and chloromethylsilyl termini were synthesized and polymerized by the AIBN-initiated radical polymerization procedure yielding a ferrocenyl dendronized polymer and a chloromethylsilyl dendronized polymer, r

Convergent dendron approach using a phenol triallyl building block: Synthesis of a phenol dendron containing 27 allyl termini

A successful convergent dendron synthesis is achieved using a phenol triallyl (AB3) building block by a sequence of reactions consisting of hydrosilylation-phenol protection. The key feature is the hydrosilylation using dimethylchloromethylsilane that avoids the side dehydrohalogenation previously found with linear branches containing β-hydrogens. The advantage of the AB3 building block is the multiplication of the dendron branches by three at each generation, which allows the synthesis of the second-generation 27-allyl phenol dendron.

Nanoscopic assemblies between supramolecular redox active metallodendrons and gold nanoparticles: Synthesis, characterization, and selective recognition of H2PO4-, HSO4-, and adenosine-5′-triphosphate (ATP2-) anions

Tri- and nonaferrocenyl thiol dendrons have been synthesized and used to assemble dendronized gold nanoparticles either by the ligand-substitution method from dodecanethiolate - gold nanoparticles (AB3 units) or Brust-type direct synthesis from a 1:1 mixture of dodecanethiol and dendronized thiol (AB9 units). The dendronized colloids are a new type of dendrimers with a gold colloidal core. Two colloids containing a nonasilylferrocenyl dendron have been made; they bear respectively 180 and 360 ferrocenyl units at the periphery. These colloids selectively recognize the anions H2PO4- and adenosine-5′-triphosphate (ATP2-) with a positive dendritic effect and can be used to titrate these anions because of the shift of the CV wave even in the presence of other anions such as Cl- and HSO4-. Recognition is monitored by the appearance of a new wave at a less positive potential in cyclic voltammetry (CV). The anion HSO4- is also recognized and titrated by the dendronized colloid containing the tris-amidoferrocenyl units, because of the progressive shift of the CV wave until the equivalence point. These dendronized colloids can form robust modified electrodes by dipping the naked Pt electrode into a CH2Cl2 solution containing the colloids. The robustness is all the better as the dendron is larger. These modified electrodes can recognize H2PO4-, ATP2- and HSO4-, be washed with minimal loss of adsorbed colloid, and be reused.

Gold nanoparticles containing redox-active supramolecular dendrons that recognize H2PO4-

Gold nanoparticles have been functionalized with thiol dendrons containing three redox active amidoferrocenyl or silylferrocenyl units; using cyclic voltammetry, these dendronized gold nanoparticles recognize H2PO4-.
