| abstract |
The invention relates to chromatographic separating media for the separation of nucleic acids, comprising a base carrier and an affinity ligand, which ligand contains a heteroaromatic rest of the formula (I), where X is -CH= or -N= and Y is -NCH3- or -O-. The invention also relates to a synthesis pathway for producing heteroaromatic oligoamides, in which the heteroaromatic amide units are introduced into a polymer support in the form of nitrated heteroaromatic carbonic acid derivatives without the need for protective groups. |
