| Outline of Final Research Achievements |
We have succeeded in synthesizing a series of new porphyrin analogues, such as calixpyrrole and cyclo[4]pyrrole, which have high macrocyclic ring strain by developing novel synthetic routes using polyketone precursors. These new porphyrinoids were used for super acid-resistant fluorescent dyes and anion receptors that undergo ring-expansion reactions upon strain. These results have made significant contributions to the elucidation of novel properties of porphyrinoids induced by ring contraction and strain and their application to materials.
