Singlet-singlet energy transfer in homo- and hetero-porphyrin dyads containing meso-tolylporphyrin and meso-furylporphyrin sub-units

The singlet-singlet energy transfer properties of series of covalently linked porphyrin dyads containing meso-tolylporphyrin as energy donor and meso-furylporphyrin as energy acceptor with different porphyrin cores are described.
