|Outline of Final Research Achievements
The compounds having strong absorption bands in the near-IR region have attracted attention due to their applicability as photosensitizer in photodynamic therapy and energy-capturing materials in solar cells. In order to meet these demands, we have designed and synthesized porphyrin, phthalocyanine, and BODIPY derivatives having strong absorption beyond 700 nm. When 8-10 pyrrole rings were linked directly to make cyclic compounds, the resultant aromatic compounds showed strong absorption in the 1300-1600 nm region. Phthalocyanines modified by sulfur, selenium, or terbium in their periphery, and phosphorus, arsenic, and antimony in the center, showed main absorption between 1000 and 1100 nm, together with fluorescence. Linearly dimerized BODIPYs showed absorption and strong fluorescence between 700 and 900 nm, suitable for the detection of cancer cells.
