| Abstract(in English) | Optical absorption spectrum, photoluminescence (PL) and electroluminescence (EL) in Poly[(tetraalkyldisilanylene)-p-oligophenylene]s (PDSiOP) are found to be dependent on the length of oligophenylene but not so much on length of short alkyl substituents such as methyl and ethyl substituents. Spectral narrowing of PL of blue in color has been observed in poly[(tetraalkyldisilanylene)-p-oligophenylene]s upon intense optical excitation due to stimulated emission. PL quenching and photoconductivity (PC) enhancement upon C_<60> doping have been commonly observed in these polymers. These characteristics were explained by taking the important role of oligophenylene units in the main chain into consideration. |
