Direct Cu(I)-catalysed coupling of a carborane to a meso-tetraphenylporphyrin

The copper-catalysed coupling of 1,2-dicarbaclosododecaborane(12) with a meso-iodophenylporphyrinatozinc has been investigated. Optimisation of the reaction conditions gave 5-(4-(1,2-dicarbaclosododecaboran(12)yl)phenyl)-10,15,20-triphenylporphyrin as its

Effects of linker torsional constraints on the rate of ground-state hole transfer in porphyrin dyads

Understanding hole/electron-transfer processes among interacting constituents of multicomponent molecular architectures is central to the fields of artificial photosynthesis and molecular electronics. Herein, we utilize a recently demonstrated 203Tl205Tl hyperfine "clocking" strategy to probe the rate of hole/electron transfer in the monocations of a series of three thallium-chelated porphyrin dyads, designated Tl2-U, Tl2-M, and Tl2-B, that are linked via diarylethynes wherein the number of ortho-dimethyl substituents on the aryl group of the linker systematically increases (none, one, and two, respectively). Variable-temperature (160-340 K) EPR studies on the monocations of the three dyads were used to examine the thermal activation behavior of the hole/electron-transfer process and reveal the following: (1) Hole/electron transfer at room temperature (295 K) slows as torsional constraints are added to the diarylethyne linker [k(Tl2-U) > k(Tl2-M) > k(Tl2-B)], with rate constants that correspond to time constants in the 2-5 ns regime. (2) As the temperature decreases, the hole/electron-transfer rates for the monocations of the three types of dyads converge and then cross over. At the lowest temperatures examined (160-170 K), the trend in the hole/electron-transfer rates is essentially reversed [k(Tl2-B) > k(Tl2-M)k(Tl2-U)]. The trends in the temperature dependence of hole/electron-transfer among the three dyads are consistent with torsional motions of the aryl rings of the linker providing for thermal activation of the process at higher temperatures in the case of the less torsionally constrained dyads, Tl2-U and Tl2-M. In the case of the most torsionally constrained dyad, Tl2-B, the hole/electron-transfer process is activationless at all temperatures studied. The reversal in rates of hole/electron transfer among the three dyads at low temperature is qualitatively explained by the results of density functional theory calculations, which predict that static electronic factors could dominate the hole/electron-transfer process when torsional dynamics are thermally diminished.

SYNTHESIS OF TETRAPHENYLPORPHINES WITH ACTIVE GROUPS IN THE PHENYL RINGS6. SYNTHESIS OF MONOSUBSTITUTED TETRAPHENYLPORPHINES BY DIAZOTIZATION

Monoaminophenyltriphenylporphines are diazotized and then used to produce monohalosubstituted tetraphenylporphines.Isomeric mono(p-hydroxyphenylazo)phenyltriphenylporphines are synthesized by replacing the azo group of diazonium salts of monosubstituted porphines with phenol.
