9(10),16(17),23(24)-Tris[4-methyl-coumarin-7-yloxy]-2(3)-(1,5-naphthalene) binuclear zinc phthalocyanine (bi-CPc) based 1,5-dihydroxynaphthalene, 4-nitro-phthalonitrile, resorcinol, ethyl acetoacetate and zinc acetate on raw material was synthesized. The structures and properties of precursors and bi-CPc were characterized by 1H NMR, FT-IR, UV-Vis, elemental analysis and thermogravimetric analysis. Results showed that strong π-π* transition was demonstrated by UV-Vis absorption spectrum of bi-CPc. At the same time, it existed in a form of monomer in solution of N,N-dimethylformamide (DMF) and possessed excellent thermal stability. Redox behavior of bi-CPc was researched by cyclic voltammetry (CV), and energy level of LUMO and HOMO of bi-CPc matched with energy level of nano-TiO2 after calculating. Through further structural modification, it is expected to use as photosensitive dye with excellent performance for solar cells.
Key words： phthalocyanine; binuclear; coumarin; dye-sensitized solar cells
