| Research Abstract |
Very large anisotropy of the absorption peaks was shown in rr-P3HT, PFO and MEH-PPV films which form polycrystalline, liquid crystalline and amorphous state, respectively. So, it is concluded that almost allπ-conjugated polymers can be highly oriented parallel to the stretching direction. The field-effect hole mobility of oriented rr-P3HT in a current flow parallel to the stretching direction was larger by a factor of 3.4 compared to that perpendicular to the stretching direction. These results indicate that charge transport via theπ-conjugated rr-P3HT chains is advantageous in the stretch-oriented rr-P3HT film.
