Abstract
Optical absorption spectrum, photoluminescence (PL) and electroluminescence (EL) in poly[(tetraalkyldisilanylene)-p-oligophenylene]s (PDSiOP) are found to be dependent on the length of the oligophenylene but not on the length of the short alkyl substituents such as methyl and ethyl substituents. Spectral narrowing of the blue PL was observed in poly[(tetraalkyldisilanylene)-p-oligophenylene]s upon intense optical excitation due to stimulated emission. PL quenching and photoconductivity (PC) enhancement upon C60 doping are commonly observed in these polymers. These characteristics were explained taking the important role of oligophenylene units in the main chain into consideration.
