摘要

Abstract

New silicon-containing phenyleneethynylene hybrid oligomers

and

were synthesized

via

Sonogashira cross-coupling reactions of ethynyl-terminated silazane monomer

′-bis(4-ethynylphenyl)-1

1-diphenylsilazane (

) and corresponding bis-(4-bromo-phenyl)-ended organosilicon unit containing monomers

respectively. These new oligomers were easily soluble in common solvents. The incorporation of flexible organosilicon units in the oligomers leads to blue-shift in both the UV-Vis absorption and fluorescence emission spectra similarly. The results of differential scanning calorimetry (DSC) indicate that the flexible units relieve the rigidity of oligomeric chain and provide favorable conformation for thermal cross-linking reactions. The oligomers show good thermal and thermal-oxidative stability from the thermogravimetric analysis (TGA)

with their decomposition temperature at 10% weight loss (

10%

) higher than 400 °C under both nitrogen and air atmosphere.
