**5. Conclusion**

The examples of complexes of photoactive compounds with CD container molecules presented in this chapter are hybrid materials created by combining two (or more) different elements of a different nature. In this context, they can be considered as a very large and heterogeneous class of materials. Such materials include molecular and supramolecular assembled materials, polymers, or nanosized objects, nanostructured and hybrid architectures with organic or biological characteristics. Such organic hybrid systems combine particular properties of the components, which explains the wide range of properties exhibited by the systems and the great possibilities in the development of methods for their synthesis.

Organic hybrid materials composed of cyclodextrin receptors and photoactive components, provide a great opportunity for improving of photophysical characteristics, increasing functionality, and extending the field of application. Supramolecular functionalization of photoactive CD molecules, which play the role of platforms for the immobilization of bioelements such as enzymes, antibodies, nucleic acids (DNA, RNA, microRNA), and other functional groups, is of great importance for the manufacture of analytical devices for biosensors. This approach can also be used to obtain novel hybrid organic photoactive materials.
