Abstract:

Porphyrin assemblies are attractive building blocks for modular construction of electronic and optical devices, chemical sensors and solar energy conversion. Functionalization of porphyrin derivatives at the meso-position has been a subject of major interest in the last decades, since it allows for the improvement of the photophysical parameters. Following on our research group’s interest on the study of the imide function in tetrapyrrolic derivatives, we have now explored the synthesis and optical properties of two new porphyrins meso-substituted with phenylmaleimide (7 and 9) (Scheme 2), prepared from the maleimide 5 (Scheme 1). Compounds 7 and 9 may constitute potential building blocks to synthesize dyads, triads or tetrads with improved photophysical and electrochemical properties for use as chemical sensors as well as photosensitizing materials.
