Synthesis and complexation of tetrathiafulvalene derivatives functionalised with [15]aneS_5 thioether crowns

摘要

Two new tetrathiafulvalene (TTF)-based molecules functionalised with [15]aneS_5 groups have been prepared by phosphite mediated coupling reactions. The [15]aneS_5-thione precursor has been characterised by X-ray crystallography. Cyclic voltammetry, spectroelectrochemistry and EPR studies of one of these TTF compounds with and without guest copper (II) ions have revealed binding of Cu~(II) and temperature dependent intramolecular electron transfer to give Cu~I and TTF~+.
