Abstract

We prepared nanorods of octabutoxyphthalocyanine (ObPc) with an average diameter of 200 nm by filling porous alumina with molten ObPc. During solidification of ObPc in the porous alumina, a magnetic field of 5 T was applied to orient the ObPc molecules in the nanorods based on the diamagnetic character of ObPc. X-Ray diffraction patterns showed that the molecular orientation partly depended on the presence and the direction of the applied magnetic field, and that it was consistent with the magnetic properties of ObPc. Since this method uses the diamagnetic character common to organic molecules, it is a versatile way to control the molecular orientation of organic nanomaterials by using a magnetic field.
