Synthesis, Electrochemical Behaviors and Anion Recognition of A Novel Star-[Polystyrene-b-poly(ferrocenyloxy ethyl acrylate)]₆with Hexafunctional Cyclotriphosphazene Core

Abstract

A novel star-[polystyrene-b-poly(ferrocenyloxy ethyl acryl ate)] 6 with hexa-functional cyclotriphosphazene core (star-(PS-bPFcEA) 6 ) was synthesized by atom -transfer radical polymerization(ATRP) and its electrochemical behaviors and anion recognition was investigated through CV. The results indicated that increasing of molecular weight resulted in obvious decreasing of reduction peak potential E pc , and the oxidation peak potential E pa kept comparatively stable. Moreover, when titrating anion H 2 PO À 4 into polymer solution, E pc increased while E pa reduced evidently, which suggested that star-(PS-b-PFcEA) 6 provided with high anion recognition capacity of H 2 PO À 4 .

Porous Carbons – Hyperbranched Polymers – Polymer Solvation

“…They concluded that the introduction of phenol groups via the nucleophilic aromatic substitution reaction of aryl fluorides with K 2 CO 3 afforded a very low-cost and efficient alternative to demethylation of the methoxy groups using either pyridine hydrochloride or BBr 3 when a large excess of reagent is used. The yields and selectivity of the reactions were also improved significantly utilizing the nucleophilic aromatic Gong et al [173] synthesized and characterized an ABB 0 -type monomer containing a pair of phenolic groups and an aryl fluoride, which was activated toward displacement by the attached oxazole ring. The ABB 0 monomer (1-34, Scheme 12) was self-condensed to form a hb poly(aryl ether oxazole) (hb-PAE-Ox) with terminal phenolic groups.…”

Apparently, the organic spacers assure solubility in organic media in both oxidation states, which allows the determination of the hydrodynamic radii by electrochemical means.…”

New Polymer Syntheses Part 57: Thermally Stable New Ferrocene‐Polyazomethines, Synthetic Methodology, and Characterization

“…The electrochemical behaviours of some ferrocene derivatives were investigated by cyclic voltammetry showing interesting behaviour [34,37,38], this encouraged us to study the electrochemical behaviour of some new polyazomethines with ferrocene moiety in the main chain. The electrochemical redox properties of the newly synthesized polyazomethines 6a-e based ferrocene moiety were studied by cyclic voltammetry at room temperature in (dry CH 2 Cl 2 : absolute ethanol, 1 : 1) solutions, using glassy carbon electrode as working electrode, Pt gauze as a counter electrode and Ag/AgCl as a reference electrode, and tetra-n-butylammonium perchlorate (TBAP) as the supporting electrolyte.…”

Synthesis of a novel branched–hyperbranched diblock polyolefin via chain walking and chain transfer polymerization from ethylene alone

“…[1][2][3] Ethylene is the simplest and most inexpensive olefin monomer, block polyolefin such as dendritic-linear block polymers, hyperbranched-linear polymers, and star-linear polymers, produced from ethylene alone is favorable for commercial utility. [1,2] For unique chain architectures, block polyelfin is readily amenable for applications as thermoplastic elastomers, compatibilizers, drug support, and high-impact plastics for its unusual compatibility, solubility, and solid-state properties.…”
