我们发现，π共轭聚合物，聚（亚芳基乙炔基），显示出极高的磁光活性与2.5 × 10（5）° T-1.m（-1）的费尔德常数在法拉第旋转测量使用静态磁场。我们还进行了测量，在regioregular聚噻吩旋涂薄膜和再现的费尔德常数最近报道使用调制技术，证明异常高的磁光活性的聚合物/有机材料。这一事实表明，分子间的π电子相互作用在这一现象中起着重要的作用。(C)2009日本应用物理学会
We found that a pi-conjugated polymer, poly(arylene ethynylene), shows extremely high magneto-optic activity with a Verdet constant of 2.5 x 10(5) deg.T-1.m(-1) in Faraday rotation measurements using a static magnetic field. We also conducted the measurements in regioregular polythiophene spincoated films and reproduced the Verdet constant recently reported using a modulation technique, certifying unusually high magneto-optic activity in polymer/organic materials. This fact suggests that the intermolecular interaction of pi-electron plays important role in this phenomenon. (C) 2009 The Japan Society of Applied Physics
