Epub 2014 Mar 20.The structures and optical properties of tris(trimethylsilyl)silylated oligothiophenes were examined by spectroscopies, theoretical calculations, and single-crystal X-ray measurements. Bathochromic shift from the original oligothiophenes was observed in the tris(trimethylsilyl)silylated ones, confirming the σ-π conjugation between Si-Si σ bonds and π-orbital. 5,5'-Bis(tris(trimethylsilyl)silyl)-2,2'-bithiophene (Si-T2) showed the highest fluorescence quantum yield (ΦF) both in solution (0.
