OLIGOMERIC COMPOUNDS THAT CONTAIN PERFLUOROALKYL, PROCESS FOR THEIR PRODUCTION, AND THEIR USE IN NMR DIAGNOSIS

摘要

Oligomeric compounds that contain perfluoroalkyl of general formula I In which • A is a molecule portion that contains 2-6 metal complexes that are connected directly or via a linker to a nitrogen atom of an annular skeleton chain, and • RF is a perfluorinated, straight-chain or branched carbon chain with formula -CnF2nE, in which E represents a terminal fluorine, chlorine, bromine, iodine, or hydrogen atom and n stands for numbers 4-30, are valuable compounds for diagnosis, especially as in-vivo contrast media.
