Abstract

UV-visible absorption and fluorescence properties of 14 nano-size star-like compounds, being composed of oligothienylene units bridged by silicon atoms, have been studied in dioxane solution. The absorption and emission maximum wavelengths are found to be dependent on the oligothienylene units. High fluorescence quantum yields and longer lifetimes are observed for the star-like compounds containing bithienylene units, being related to the σ–π interaction and the star-like structure.
