Paola Ceroni is an Associate Professor at the University of Bologna. In 1998, she obtained her Ph.D. in Chemical Sciences at the University of Bologna, after a period in the USA (Professor Allen J. Bard's laboratory). Paola Ceroni's research focusses on the photochemistry and electrochemistry of molecular and supramolecular systems, with particular emphasis on photoactive dendrimers. She is a co-author of about 100 scientific papers in refereed international journals.



Margherita Venturi is a full Professor of Chemistry at the University of Bologna. She started her career at the National Research Council in Bologna, where she used radiolytic techniques to study the mechanisms involved in model systems for the conversion of solar energy. Her present research is focussed on the design, construction, and characterization of molecular-level devices and machines in the context of the bottom-up approach to nanotechnology. She is a co-author of more than 190 publications in international journals, including several reviews and two monographs.

Abstract

The initial interest in dendrimer chemistry was the synthesis of such aesthetically pleasant macromolecules. Nowadays, the field is moving to applications in various multidisciplinary areas, such as medicine, biology, chemistry, physics, and engineering, i.e. at the interface of many disciplines. This short review describes some promising applications of photoactive and electroactive dendrimers as artificial enzymes, molecular batteries, sensors with signal amplification, photoswitchable hosts, systems for energy up-conversion, and light-harvesting antennas. The reported examples clearly show that these applications take advantage of the unique aspects of dendrimer structure: (i) three-dimensional array; (ii) generation-dependent size; (iii) presence of selected functional units in predetermined sites; and (iv) endo- and exo-receptor capabilities.
