  Energy transfer pathways in pyridylporphyrin Re(I) adducts

  摘要：

  Dimeric and pentameric adducts between a meso-4' pyridylporphyrin core and either one or four rhenium(l) bipyridine tricarbonyl units, fac-[Re(CO)(3)(bipy)(4'MPyP)][CF3SO3] and fac-[{Re(CO)(3)(bipy)}(4)(4'TPyP)][CF3SO3](4)(4'MPyP = 4'-monopyridylporphyrin, 4'TPyP = 4'-tetrapyridylporphyrin), respectively, were synthesized and their photophysical behaviors were investigated by emission and absorption time resolved experiments. The adducts exhibit distinctive supramolecular features, different from those of the molecular components. Upon excitation of the core, the typical porphyrin fluorescence is quenched. This effect is attributed to enhanced intersystem crossing in the porphyrin unit, owing to the heavy atom effect provided by the attached rhenium unit(s). Following excitation of rhenium fragments the typical rhenium MLCT emission is not observed while partial sensitization of the porphyrin fluorescence occurs, indicating that fast intercomponent energy and/or electron transfer processes take place in competition with the intersystem crossing in the rhenium unit.

  We demonstrate here that, whereas the rhenium(I)-zinc porphyrin dyad fac-[Re(CO)(3)(bpy)(Zn center dot 4'MPyP)] (CF3SO3) [1; 4'MPyP = 5-(4'-pyridyl)-10,15,20-triphenylporphyrin] shows no evidence for photoinduced electron transfer upon excitation in the visible region because the charge-separated state ZnP+-Re- is almost isoenergetic with the singlet excited state of the zinc porphyrin (Delta G = -0.05 eV), the introduction of electron-withdrawing ethyl ester groups on the bpy ligand significantly improves the thermodynamics of the process (Delta G = -0.42 eV). As a consequence, in the new dyad fac-[Re(CO)(3)(4,4'-DEC-bpy)(Zn center dot 4'MPyP)] (CF3SO3) (4; 4,4'-DEC-bpy = 4,4'-diethoxycarbonyl-2,2'-bipyridine), an efficient and ultrafast intramolecular electron-transfer process occurs from the excited zinc porphyrin to the rhenium unit upon excitation with visible light. Conversely, the introduction of electron-donor tert-butyl groups on the meso-phenyl moieties of the zinc porphyrin has a negligible effect on the photophysics of the system. For dyad 4, the time constants for the charge-separation and charge-recombination processes in solvents of different polarity (PrCN, DCM, and toluene) were measured by an ultrafast time-resolved absorption technique (lambda(exc) = 560 nm).
• Structural and Photophysical Characterization of Multichromophoric Pyridylporphyrin-Rhenium(I) Conjugates

  Four porphyrin-Re(I) conjugates, in which a pyridylporphyrin chromophore is directly coordinated to the electron-acceptor fragment [fac-Re(CO)(3)(bipy)](+), were prepared: the dimeric and pentameric compounds [fac-Re(CO)(3)(bipy)(4'MPyP)](CF3SO3) (1) (4'MPyP = 4'-monopyridylporphyrin) and [fac-Re(CO)(3)(bipy)}(4)(mu-4'TPyP)]-(CF3SO3)(4) (2) (4'TPyP = 4'-tetrapyridylporphyrin), and the corresponding compounds with 3' rather than 4' porphyrins, [fac-Re(CO)(3)(bipy)(3'MPyP)](CF3SO3) (3) and [fac-Re(CO)(3)(bipy)}(4)(mu-3'TPyP)](CF3SO3)(4) (4). These adducts proved to be very stable in solution and were also structurally characterized in the solid state by X-ray crystallography. A detailed photophysical study was performed on the zincated adducts of the conjugates 1-3, labeled 5, 6, and 7, respectively. In all adducts the typical fluorescence of the zinc-porphyrin unit was reduced in intensity and lifetime by the presence of the peripheral rhenium-bipy fragment(s) (heavy-atom effect). For the dyads 5 and 7 the photoinduced charge transfer process from the zinc-porphyrin to the Re(I)-bipy unit is only slightly exoergonic. Ultrafast spectroscopy experiments showed no evidence for electron transfer quenching in the dyads as such, whereas the addition of pyridine (that binds axially to zinc and thus affects the porphyrin redox potential) led to a moderately efficient photoinduced electron transfer process. In perspective, an appropriate functionalization of the bipy ligand and/or of the porphyrin chromophore might improve the thermodynamics and, thus the efficiency, of the photoinduced electron transfer process.
