Abstract

The 2,12 pyrrole positions of meso-tetraphenylporphyrin were functionalized through triple carbon-carbon bonds by C60 and ferrocene giving new electron donor-acceptor triads which have been characterized and studied by photophysical methods. The fluorescence spectra of the new compounds have been compared to those previously reported for similar compounds giving as a result an increase of the quantum efficiency based on the larger separation of fullerene from the porphyrin ring. On the contrary the efficiency decreases with the presence of a phenylene spacer between ferrocene and the macrocycle.
