| Research Abstract |
Dendrimer with insoluble chromophore have attracted considerable attention because of the flexibility of molecular design for functional materials. We have reported the synthesis of dendron-functionalized fullerene and cadmium chalcogenide. They are soluble in various solvents and act as effective photosensitizers to generate singlet oxygen.Meanwhile, hexathiopentacene has been studied as an active material in OFETs because of its high hole transport mobility. However, hexathiopentacene is insoluble in organic solvents, Hence the properties of the hexathiopentacene in solution are still unclear, i.e., NMR, UV-Vis, and fluorescence spectra of the solution of hexathiopentacene at room temperature have never been reported. Here we present the synthesis of hexathiopentacene dendrimer together with photooxygenation reaction using hexathiopentacene dendrimer as a photosensitizer of singlet oxygen.
