Simultaneous measurement of molecular orientation and current as a function of voltage has been conducted. Molecular orientation was measured using the polarization dependence of intramolecular electronic transition. In ITO/poly(3-hexylthiophene)/Al structure, it was found that the molecular orientation change assists the hysteretic current-voltage (J-V) characteristics. The result indicates that this measuring method can be useful in investigating the effects of molecular orientation change on unusual J-V characteristics.
