Abstract
A vanadyl phthalocyanine (VOPc) film (Phase I) on a mica substrate was prepared and photoinduced phase transition of VOPc was tried. Changes in absorption spectra show that Phase I structure is converted to Pha se II structure by the irradiation with He-Ne laser. The surface struc tural changes of VOPc were also observed by using atomic force microsc opy (AFM). Experimental results suggest that the phase transition was induced by photo-thermal processes.
