초록
We have investigated a molecular orientation effect of septithiophene(7T), the conjugated linear septenary of thiophene, on its optical and electrical properties. Vacuum evaporation of septithiophene on a substrate induces a upright orientation. We rubbed the pre-layer to lie down molecules. As a result, we could get a horizontal molecular orientation. Dichroic ratio is about 2 at 418nm from UV/visible absorption spectrum. To investigate the electrical characteristics, we fabricated devices with septithiophene as a semiconducting material. The conductivity with horizontal septithiophene orientation is about one order gloater than that of upright septithiophene.
