Design, synthesis and characterization of monomolecular interfacial layers

Use of Zirconium−Phosphate−Carbonate Chemistry to Immobilize Polycyclic Aromatic Hydrocarbons on Boron-Doped Diamond

“…A great deal of work has been devoted to the development of organized molecular systems that can be bound to interfaces either ionically or covalently. ,− Among the most widely used methods for the creation of layered interfacial structures are Langmuir−Blodgett deposition and self-assembly. − Both of these interface formation methodologies can be performed on a variety of substrates, conductive as well as insulating. The resulting mono- or multilayer structures can be bound to the substrate through any of a variety of methods, including the formation of covalent bonds, , physisorption, or ionic coordination chemistry. − We report here on the application of zirconium phosphate/phosphonate (ZP) chemistry, pioneered by the Mallouk, Thompson, and Katz groups, − to attach molecules to BDD.…”

Fluorescence Signaling of Zr4+by Hydrogen Peroxide Assisted Selective Desulfurization of Thioamide

“…However, Fe 3+ and Cu 2+ ions are found to significantly interfere with the Zr 4+ -selective signaling due to the Fenton-like reaction with added H 2 O 2 . , Possible influence of coexisting anions on the signaling was also examined (Figure S6, Supporting Information). Almost no interferences were observed with commonly encountered anions except for SO 4 2– and H 2 PO 4 2– , which might be due to the hydrolysis of zirconium sulfate and formation of insoluble zirconium phosphate ( K sp of Zr 3 (PO 4 ) 4 = 1 × 10 –132 ) . Signaling of Zr 4+ by probe 1 was completed within 10 min (Figure ).…”
