Abstract
Mesoporous silica (MPS) precursor films containing a polymer template were photochemically micropatterned by means of ultraviolet (VUV) irradiation. The resulting 10-m-width micropatterns consisted of MPS and MPS precursor regions. We further modified the latter surfaces using a fluoroalkylsilane. Due to this site-selective hydrophobization, rhodamine 6G molecules dissolved in water were successfully doped selectively into the irradiated MPS regions, as evidenced by absorption and fluorescence spectroscopy, and fluorescence microscope observation.
