Synthesis of organosilanylene–thienylene alternating oligomers bearing ether side chains

Organosilanylene–thienylene alternating oligomers bearing ether side chains were synthesized and their optical properties were studied. The oligomers exhibited the emission maxima at 380–400 nm, which were slightly shifted to lower energies as the solvent polarity increased. In contrast, the UV absorption spectra were not evidently affected by the solvent polarity, indicating that the solvatochromic behaviors in the emission spectra may be due to the favored aggregation of chromophores in the polar solvents.
