Synthesis of thiol substituted oligoanilines for molecular device candidates
摘要:
The synthesis of thioacetate derivatized oligoanilines designed for molecular electronic device purposes is described. Reversible oxidation between the non-conductive leuco base and conductive emeraldine salt forms of these compounds may produce switching effects and device behavior. The targeted compounds contain a sulfur moiety as a means to connect the molecules to metallic electrodes. (C) 2003 Elsevier Ltd. All rights reserved.

The palladium-catalyzedamination of aryl halides, in conjunction with an orthogonal protective group scheme, forms the basis of two routes to oligoaniline precursors. One method consists of a bidirectional chain growth from a symmetric core piece, whereas the other involves a divergent−convergent synthesis of nonsymmetric fragments, followed by coupling to a symmetric core fragment. The oligoaniline
