| Outline of Final Research Achievements |
Colloidal nanoparticle of pharmaceuticals might have improved stability and sustainability in the body than those of the common solution-state of drugs. We envisaged that the encapsulation of target drugs by capsule-shaped organic molecules with fluorine or fluorinated functional groups at their peri-positions should be a potential strategy to realize this idea. Phthalocyanines and subphthalocyanine known as organic dyes were selected as the templates of capsule molecules, which should be functionalized by fluorinated functional groups. After many attempts, we succeeded the synthesis of fluorinated phthalocyanines, subphthalocyanines and their hybrid compounds. These dyes show unique aggregation-state depend on their solvents. X-Ray crystallographic analysis and/or molecular calculations revealed their capsule-shaped structures. Photodynamic therapy experiments of selected fluorinated dyes were examined and showed interesting biological activities.
