The invention relates to novel cationic amphiphiles having an aromatic ring comprising at least one nitrogen atom. The cationic amphiphiles are particularly useful for the introduction of biologically compounds such as DNA, RNA, proteins and the like into eukaryotic cells. The cationic amphiphiles are represented by the following basic formula:(I). Characteristic is that R
1
and R
2 ?are single C6-C24 carbon chains. For the mode of action it is assumed that R
1
folds back over the aromatic ring towards R
2
.
