Abstract
  • The search for new chromophores exhibiting photo and electro-active properties which can complement or replicate the characteristics of already known dyes to be used in the construction of functional molecular arrays is an important topic of today's synthetic and physical chemistry. Following a bio mimetic approach, the class of porphyrins has been for a long time the most used in the construction of arrays for light energy collection and conversion. However, other porphyrinoids have proven to be viable alternatives to simple porphyrins in the construction of photo-active dyads or higher homologues. In this context, we have been engaged over the last few years in the study of the photophysical properties of free-base corroles [1] and their potential application in the construction of assemblies with useful photo-induced properties. Corroles are synthetic aromatic macrocycles of the tetrapyrrolic family. Recently synthetic breakthroughs and subsequent developments made these compounds readily available. In the last years the interest in these compounds has grown as well as the number of their applications which span from anti tumor therapeutic properties to catalytic and sensor applications. From a photophysical viewpoint they are interesting since they are photo-stable, display high luminescence, can sensitise singlet oxygen, have singlet and triplet excited states with well characterized spectra and can be easily oxidized and reduced. We report here on the photophysical characterization of various newly synthesised dyads formed by free-base corroles covalently linked to photo-active partners like free-base porphyrins, 1,8-napthalimides and perylene bisimides. The results indicate that very efficient energy transfer and/or electron transfer processes occur in these dyads. More complex arrays actually under investigation will be briefly described. (literal)
