| Outline of Final Research Achievements |
The major target of this project utilizing tripyrrine precursors was switched to development of a wide variety of three-dimensional π-systems. As a result, it was successfully achieved that novel three-dimensionalπ-electronic modes bearing a branchedπ-plane had been constructed based on peculiar nucleophilic substitution reactions onto recombined N-fused pentaphyrin bromide. In the meantime, meso-trifluoromethyl substituted octaalkylporphyrins were obtained by scrambling side reactions of oligo-pyrrolic precursors. The strongly electron-withdrawing nature and the spatial steric hindrance of trifluoromethyl group caused a large distortion of the macrocyclic plane and improvement of the absorption property. Furthermore, the trifluoromethyl groups undertook solvolysis when the centeral metal ion was zinc, affording meso-methoxycarbonyl derivatives.
