formation behavior is closely related to the structure of the azo compounds, excitation wavelength, and light polarization conditions. The absorption band position of the π–π* transition is mainly determined by the electron-withdrawing groups on the azo chromophores. When the excitation wavelength is between λmax and the band tail at the longer wavelength side, the self-structured surface patterns can be
