Chemistry of viologens

Pointing out electron acceptor properties of viologens, the outlines of porphyrin-viologen systems, complexes of viologens with donors and polymeric viologens are described along with biological interest of viologens

Rotaxanes Containing Quaternary Azaaromatic Moieties

In the paper at first rotaxanes are briefly described, then rotaxanes bearing quaternary azaaromatic moiety in the thread are presented followed by those containing quaternary azaaromatic moiety in the ring.

Supramolecular Species Bearing Quaternary Azaaromatic Moieties

In the paper at first rotaxanes are presented; these species are divided into three classes, i.e. those containing electron donor, electron acceptor and cyclodextrin molecules as rings. In following parts examples of catenanes, pretzelanes and molecular clips are described.
