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 Phase II structure by the irradiation with He-Ne laser. The surface structural changes of VOPc were also observed by using atomic force microscopy (AFM) Experimental results suggest that the phase transition was induced by photo-thermal processes.
