Abstract:

Porphyrin systems bearing fused rings have been a subject of intense research, since they constitute a viable approach to obtain new compounds with improved photophysical and photobiological properties. New β-fused uracil-porphyrin conjugates were synthesized by the tetramerization of uracil-pyrroles under acidic conditions, followed by oxidation. Complexation effects were also studied as well as aggregation in solution. Preliminary photophysical experiments were also performed in order to evaluate the potential of these new compounds for use in PDT, materials science or as fluorescent markers.
