✦ Synopsis

The excited-state properties of heterodimers of tetra( Ccarboxyphenyl)porphyrin (TPPC) and tetra(N-methylpyridyl)porphyrin (TMPyP) are studied by absorption and emission spectroscopy, EPR and zero-field ODMR. The excited singlet and triplet states of dimers formed by pairing HzTPPC with HzTMPyP or ZnTMPyP are localized on H?TPPC. The dimers formed by pairing H,TPPC with CuTMPyP and H,TMPyP with ZnTPPC or CuTPPC are non-fluorescent due to intramolecular electron transfer.

Fluorescent dimers allow the direct determination of their thermodynamic properties from kinetic analysis of the temperaturedependent two-exponential fluorescence decay of the monomer-dimer system. Monomers and dimers of tetra(carboxyphenyl)porphine in water at pH= 8 have lifetimes of 8.9 f 0.2 and

Picosecond as well as femtosecond transient absorption measurements have been performed on eight water-soluble heterodimers consisting of combinations of oppositely charged free base and metal porphyrins which have been electrochemically characterized. The ultrafast non-exponential absorption increa
