Viologen-based Supramolecular Structures

Abstract

In the paper the introduction pointing out the important role of viologens is followed by two chapters concerning rotaxanes with a thread incorporating viologens, and those with a ring built from viologens. In the next two chapters dendrimers containing viologens as a core and those with viologens localized in their apical positions are presented. The fifth chapter deals with viologens noncovalently bound with cucurbiturils, calixarenes and cyclodextrins. The final chapter shows other viologen containing compounds; it mainly concerns assemblies of their nanostructured films.
