Polymer-modified electrodes. Electrochemical and photoelectrochemical polymerization of 1-vinylpyrene

Abstract: Polymerization of 1-vinylpyrene in acetonitrile was achieved electrochemically at a conducting Sn02 electrode by application of anodic potentials and photoelectrochemically at a n-GaAs semiconductor electrode under visible light irradiation. Both polymers exhibited characteristic excimer emission (Xmal 480 nm) in both films and THF solutions similar to poly(vinylpyrene) synthesized by using Ziegler-Natta catalyst. The lifetime of the excimer emission was ~110 ns. The mechanism of photodegradation of poly(vinyl… Show more

“…Covalent attachment of pyrene and ferrocene to ITO was achieved by immersing clean ITO samples in toluene solutions of 1-vinylpyrene or ( n Bu) 2 O solutions of vinylferrocene at 80 °C for 24 h to yield pyrene-modified ITO (ITO|Pyr) and ferrocene-modified ITO (ITO|vinylferrocene). Vinyl functionalities are commonly grafted onto metal oxide surfaces via cathodic electropolymerization or exposure to UV light. , Recent studies on the attachment of alkenes and alkynes to hydroxyl-terminated surfaces using heat found that a thermal approach leads to covalently bound monolayers as opposed to polymerized multilayers . A thermal attachment approach was therefore chosen for this study to avoid multilayer formation of the covalently linked species.…”

“…Later the concept was extended to other SCs and CPs; thus assemblies such as CdS/PPy [201], CdS/PMT [202], GaAs/PMT [203,204], GaAs/PVP [205], and CuInS 2 /PPy [206] have been realized. Subsequently hybrids based on flat oxide SCs, initially TiO 2 /PPy [207,208], ZnO/PPy [209], and more recently Nb 2 O 5 [210], [211], WO 3 [137] based composites were also obtained.…”

“…This hypothesis was also supported by the fact that polymerization could proceed with electrophilic monomers rather than with styrene . In 1985, Kamat reported an n-type GaAs electrode photopolymerization of 1-vinylpyrene under visible light . Due to the small band gap of GaAs electrodes (∼1.4 eV), polymerization could be operated under visible light.…”
