Abstract

original image

Wired for action: An alumina-based template method produces nanowires of an alkylated mononuclear spin-crossover FeIII complex. The wires can be isolated by dissolving the template in acid without decomposition of the product, and have a narrow distribution of diameter widths in the range of 80–100 nm. Electronic characterization of a single wire is possible by using Raman spectroscopy coupled to AFM (see picture).
