After a definition of and an introduction into supramolecular structures strategies are developed which lead to new material properties. The specific research topics discussed in this context and with this aim include chromoionophores, molecular switches, large cavities embraced by
one or more azobenzene units and macrocyclic polyenes. It is demonstrated how light absorption can be manipulated by structural variations of the host structures and of the corresponding supramolecular complexes. The discussion is extended to new dyestuffs bearing small and large cavities,
the light absorption of which can be manipulated and even switched selectively by matching metal ions and organic particles (host/guest interaction).
