The organic materials have been widely studied for optoelectronic device applications such as organic display, laser, and organic field effect transistors. Recently, controlling molecular arrangement in organic single crystal is gathering great attention since it is one of the most important factor for modulation of the electrical and optical properties. So, many researches have studied polymorph single crystal in solution phase by solvent molecules effect. Here, we present anthraquinone disk was synthetized from anthracene disks through photooxidation of anthracene molecules in ambient condition. Upon ultraviolet (> 300 nm) light illumination in the presence of oxygen, the anthracene with monoclinic structure rearrange to the anthraquione wire with orthorhombic structure. The photoluminescence property shows definite difference between anthracene disk and anthraquinone disk which is also different with that of anthraquionoe powder. The anthraquinone disk presents red photoluminescence which is attributed to the changed molecular arrangement.
