Abstract
Two-dimensional starlike molecule 7 consisting of benzothiadiazole-thiophenylphenyltriazine groups and pentamethyldisilanyl substituted thienylene units that extend to three directions was synthesized by the reactions of 2,4,6-tris[4-(4-hexyl-5-(7-(3-hexyl-5-iodothiophen-2-yl)benzo[c][1,2,5]thiadiazol-4-yl)-thiophen-2-yl)phenyl]-1,3,5-triazine (5) with the pentamethyldisilanylthienyl substituted stannyl derivative (6). UV-visible absorption and fluorescence properties of starlike molecules 4and 7 have been investigated in dioxane and in the solid state. The application of TiO2-electrode coated on the surface with the use of 7 to dye-sensitized solar cells has been discussed.
