Electron-rich ligands with multiple tetrathiafulvalene arms
摘要:
We have synthesized a series of oligodentate ligands, the structure of which consists of a central aromatic core and three or four tetrathiafulvalene-based arms. Their syntheses exploited a simple general protocol based on the reaction of a bromomethylated core with a thiolate generated in situ from an appropriate tetrathiafulvalene precursor. According to molecular modeling, proper positioning of the fulvalene arms over the central platform gives rise to an electron-rich cavity suitable for inclusion of spatial electron-deficient guests such as fullerenes.
