| Popis: | Spectral properties and photostability of the 5,5’-6,6‘-tetrachloro-1,1‘-dioctyl-3,3‘-bis-(3-carboxypropyl)- benzimidacarbocyanine (Dye1)J-aggregate was investigated in solution and upon adsorption onTiO2nano-particles. Dye1was found to photodegrade on the surface ofTiO2. Additionally, the self-assembly of Dye1was studied on a glass surface by non-contact atomic force microscopy (NCAFM). The dye molecules form a well-defined fiber like structure that extends for tens of micrometers. The internal structure of the fibers was clearly resolved and showed a number of small tubes wrapped around each other to form a helical structure. |
