Thiophene oligomers have received considerable attention due to their unique optical and electronic properties. Soluble dimethyl-n-octylsilyl end-capped arene-thiophene oligomers with central unit such as phenyl, biphenyl, fluorene and naphthalene were synthesized by Stille reaction. The optical, electrochemical and thermal properties of these oligomers were measured. The absorption maxima of arene-thiophene oligomers in dilute solutions are close to those obtained for DSi-4T(labs = 403 nm) and exhibit well-resolved fluorescence spectra in solution with emission maxima at 445 nm, 446 nm, 448 nm and 450 nm for DSi-TTPTT, DSi-TTPPTT, DSi-TTFTT, and DSi-TTNTT, respectively. |
