摘要

The steric tacticity of polyphenylsilsesquioxanes (PPS) was studied by exeimer fluorescence spectroscopy. It was found that the fluorescence of PPS come mainly from its intramolecular excimers

The experimental results indicated that the steric-structure of PPS is most probably cisisotactic rather than the cis-syndiotactic as suggested in the literature. With the increase in defect content monomer fluorescence intensity increases because of the enhanced mobility of phenyl groups. Molecular weights and molecular weight distributions do not affect the fluorescence spectra of PPS.
