By combining characteristic supramolecular buildung blocks, synthetic tricks, and the stereochemical know-how of some leading European groups in the present project it will be possible to prepare new catenanes, rotaxanes, and more complex supramolecular species showing new stereochemical features and exhibiting new material properties. In the foreground are topologically chiral species like catenanes and pretzelanes of a mixed hybrid type as well as cycloenantiomeric and cyclodiastereomeric rotaxanes which contain at the same time phenanthroline- and amide-units in their skeleton. They will be assembled to larger chiral scaffolds and used for further template reactions. Their synthesis will be for the first time carried out stereoselectively. From these studies new knowledge of supramolecular syntheses, of topological chirality and of complex supramolecules and of structure-chiroptics dependendies is expected to emerge, as well as new insights into mechanical bonding of molecules.
