“…The straightforward strategy consists of substituting the TTF core with one or more coordination functionalities and to use this building block as an electroactive ligand with various metal ions. Within this frame, the use of dithiolates [2] and phosphines [3][4][5][6] as well as pyridine [7][8][9][10] and related ligands have received a great deal of attention as compared to b-diketonate ligands, which offer quite a unique chelating ability with a large variety of metal centers [13]. Along these lines, we recently described the synthesis of TTF 1 substituted by a thioacetylacetone function (TTFSacacH) and demonstrated the chelating ability of its acetylacetonate ions (TTFSacac) towards metal (II) centers (M = Ni and Zn) [11,14].…”
