We synthesized [poly(2,5-bis(trimethylsilyl)-1,4-phenylenevinylene)] (BTMS-PPV) via two different precursor polymers, i.e., a water-soluble sulfonium and an organic soluble thiophenoxy precursor polymers, and compared their properties with each other. The thiophenoxy precursor polymer shows a good thermal stability and it is eliminated from 320 °C. BTMS-PPV film through the thiophenoxy precursor route shows a blue-shifted UV-visible absorption and PL emission spectra compared with those from the water-soluble precursor route. A single layer EL device fabricated with BTMS-PPV from the thiophenoxy precursor polymer as an emitting layer shows the threshold voltage of 20 V and the emission maximum at about 545 nm. The external quantum efficiency of the device is greater than 6.0 × 10−4 % photons per electron in air and room temperature condition. [ABSTRACT FROM AUTHOR] |
