Oligomeric compounds that contain perfluoralkyl process for their production and their use in nmr diagnosis

摘要

Perfluoroalkylated oligomer compounds have the general formula (I) A-RF, in which A is a molecular fraction with 2-6 metal complexes bonded to an annular structural chain directly or via a linker with a nitrogen atom; and RF is a perfluorinated, straight-chain or branched carbon chain of formula CnF2nE, in which is a terminal fluorine, chlorine, bromine, iodine or hydrogen atom and n equals 4-30. These compounds are valuable for diagnosis, in particular as in-vivo contrasting agents.
