Preparation, Characterization and Voltammetric Aspects of a Silsesquioxane Organofunctionalized With Imidazole Groups and Subsequent Reaction With Silver and Potassium Hexacyanoferrate (III)

Abstract

This paper describes the interaction of a octa (3-chloropropyl)octasilsesquioxane (SS) functionalized with imidazole (SSI) groups, and its subsequent reaction with silver (AgSSI) and hexacyanoferrate (III) (AgHSSI). The materials SS, SSI were characterized by infrared (FTIR); solid state 13 C and 29 Si nuclear magnetic resonance (NMR). The AgSSI and AgHSSI were characterized by electronic (Uv-Vis) and infrared spectroscopy (FTIR). The AgHSSI was incorporated into a graphite paste electrode and the electrochemical studies were conducted with cyclic voltammetry. The AgSSI system was studied first, followed by the AgHSSI. The spectroscopic studies reveals that preparation was conducted with success.

β‐Cyclodextrin PAMAM Dendrimer Surface Doped with Silver and Hexacyanoferrate (III) and its Applications for Dopamine Detection in Synthetic Samples

“…There was an electrostatic interaction between the reactive groups of β‐CD‐PAMAM and hexacyanoferrate ion (cation) [Fe(CN) 6 ] 3− , while silver acts as a proton possible attached to the PAMAM N site or β‐CD O site. [46].…”

A Silsesquioxane Organically Modified with 4‐Amino‐5‐(4‐pyridyl)‐4H‐1,2,4‐triazole‐3‐thiol: Thermal Behavior and Its Electrochemical Detection of Sulfhydryl Compounds

“…In the literature some papers on hybrid and soluble silsesquioxanes with defined and undefined structures containing charged organic group were already reported, dealing with the development of electrochemical sensors [11,25]. To the best of our knowledge, the electroanalytical applications of chemically modifiedcubic silsesquioxane have been only mentioned by Do Carmo research group [26,27].…”
