Abstract

Electrochemical oxidation of [C₁₀H₁₀N] ₂[Pt(ox)₂] • H₂O (1) (C₁₀H ₁₀N = N-methylisoquinolinium, ox = oxalate) lead to the simple and rapid synthesis of nanowires of formula [C₁₀H₁₀N] _1.6[Pt(ox)₂] • 3H₂O (2) with sub-micron diameters. The partially oxidized platinum polymer 2 was examined via electron microscopy and wires with diameters of less than 5 nm were observed. The bulk electrical properties of the wires were investigated via impedance spectroscopy. Electrochemical oxidation of [C₁₀H₁₀N] ₂[Pt(ox)₂] • H₂O (1) (C₁₀H ₁₀N = N-methylisoquinolinium, ox = oxalate) leads to the synthesis of new partially oxidized platinum nanowires of formula [C₁₀H ₁₀N]_1.6[Pt(ox)₂] • 3H₂O (2). The nanowires were characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Wires with diameters of less than 5 nm and lengths of over 1 μm were observed. Energy dispersive spectroscopy (EDS) and microanalysis confirmed the degree of partial oxidation of the nanowires. The bulk electrical properties including phase angle and real and imaginary impedance values were measured and a model of the electrical conduction circuit was proposed. The significance of this work is that the large N-methylisoquilolinium cation leads to nanostructures, possibly involving individual molecular wires which has not been previously observed in the bis(oxalato)platinate nanowire system.
