ABSTRACT:
There is disclosed a synthetic method of mixing a soluble poly(1,4-phenylenvinylene) (PPV) derivative in which two silyl groups are substituted, and an electroluminescent device using the same. In the poly[2,5-bis(dimethyloctylsilyl)-1,4-phenylenvinylene] (BDMOS-PPV) according to the present invention, the final polymer is easily dissolved in common organic solvents and shows a measured absolute PL quantum efficiency of 60% much higher than that of the conventional PPV having 25%, thus making it possible to be applied as material of an electroluminescent device. Also, it provides an outstanding advantage that it can be applied to a flexible light-emitting device.
