Two-step template method for synthesis of axis-length-controlled porphyrin-containing hollow structures

π-Conjugated porphyrin-containing hollow structures with defined axis-length were successfully synthesized by a two-step template method, i.e., template-Assisted cyclization and oligomerization. During the oligomerization, templates played important roles in controlling the reaction rates and the axis lengths. The hollow structures exhibited an extended effective π-conjugation because of the high coplanarity between porphyrins.

Recognition of imidazoles by strapped zinc(II) porphyrin receptors: Insight into the induced-fit mechanism

Imidazole-porphyrin coordination has become an important tool in the design of self-assembled materials. A combination of spectrophotometric and stopped-flow techniques has been used to gain insight into the control of imidazole binding in the distal pocket of phenanthroline-strapped porphyrins. The binding studies of a variety of imidazole substrates in combination with both hindered and accessible receptors have permitted the determination of the thermodynamic and kinetic parameters associated with the imidazole binding.

KINETICS OF COMPLEX FORMATION BETWEEN ZINC MESO-TETRAPHENYLPORPHYRIN AND SOME NITROGEN BASES IN APROTIC SOLVENTS, STUDIED BY AN IMPROVED MICROWAVE TEMPERATURE-JUMP METHOD

Rate and equilibrium constants have been determined over a range temperature for the reactions of zinc meso-tetraphenylporphyrin with pyridine (in chlorobenzene, 1-chlorobutane and toluene), with 2-methylpyridine (in 1-chlorobutane), and with imidazole (in 1-chlorobutane).Rates were measured by means of an improved microwave temperature-jump apparatus incorporating signal-averaging, and at low temperatures by the stopped-flow method, with spectrophotometric detection.The forward rate constants are lower by about an order of magnitude than the values calculated for diffusion control from the simple Smoluchowsky model.A two-step mechanis appears likely.Solvent and steric effects on the rate are discussed.
