C,N-2-[(dimethylamino)methyl]phenylplatinum complexes functionalized with C-60 as macromolecular building blocks

The application of platinum(II) complexes based on the N,N-dimethylbenzylam ine ligand (abbreviated as H-C,N) in macromolecular synthesis was demonstra ted. Two cationic C,N-platinum moieties were linked with a 4,4'-bipyridine bridge, giving [{C6H4(CH2NMe2)-2-Pt(PPh3)}(2)(4,4'-bpy)](BF4)(2) (2), the c rystal structure of which was determined. To introduce C-60 groups into thi s assembly, [1,2]-methanofullerene-substituted H-C,N ligands were prepared and platinated using cis-PtCl2(DMSO)(2). Application of the methanofulleren e C,N platinum complexes in the preparation of macrostructures afforded ins oluble compounds. Therefore, phosphine ligands containing perfluoroalkyl gr oups were introduced into the fullerene-based complexes via a ligand exchan ge reaction. These fluorous complexes showed enhanced solubility in organic and fluorinated solvents. A soluble bismethanofullerene C,N-platinum(II) s tructure with a 4,4'-bipyridine bridge was obtained using these fluorinated fullerenes.
