    Abstract

    Fabrication of honeycomb-patterned microporous films (honeycomb films) by casting dilute solution of several types of polymers under high humidity has been already reported. In order to realize photofunctional materials, composites were formed by introducing mixture of two kinds of luminescent monodisperse nanoparticles (NPs) into micropores of the honeycomb film fixed on a substrate. As indicated in Figure, hexagonal or tetragonal arrays of NPs were formed in the micropores of the composites. Average number of the NPs in the micropores was estimated to be 130 by scanning electron microscopic images (average diameters of NP and micropore are 600 nm and 8 μm, respectively). Composites with different NP diameters and different micropore sizes have been fabricated to control number of NPs in a micropore. Emission spectra of the individual micropores will be measured.
