| Outline of Final Research Achievements |
The effects of main-group elements in the synthesis and properties of azaporphyrins have been investigated. The tetraazaporphyrin phosphorus(V) complex was reduced by addition of base, and extremely air-stable neutral radical (formally 19π electrons) could be isolated. Two novel synthetic reactions mediated sulfur have been developed. 1. A diamino-beta-isoindigo skeleton was obtained directly from phthalonitriles, and a new antiaromatic expanded phthalocyanine skeleton (pentabenzotriazasmaragdyrin, PBTAS) was obtained by the condensation with such isoindigo and other phthalonitrile. 2. Three-component coupling reaction of element sulfur, organometallic reagents, and phthalonitrile was developed, and functionalized phthalocyanines that have an intense absorption band in the near-IR region have been synthesized. Electron-withdrawing phthalocyanines were synthesized by lead-mediated reactions. Some metal complexes have high efficiency of singlet oxygen generation.
