Synthesis of Organosilanylene−Thienylene Alternating Oligomers Bearing Ether Side Chains. Peculiar Solvatochromic Behavior in Their Fluorescence Spectra

Organosilanylene−thienylene alternating oligomers bearing ether side chains were synthesized, and their optical properties were studied. The oligomers exhibited clear solvatochromic shifts in the fluorescence maxima, probably due to the changes in the oligomer conformations, and the emission maxima moved to longer wavelength as the solvent polarity increased.
