Polymer inverse opals were fabricated by directly infiltrating a molten polymer into silica opal templates at an elevated temperature. The main-chain π-conjugated polymer, poly[2-(9′,9′-dihexylfluorenyl)-1,4-phenylenevinylene] (DHF-PPV) was adopted for fabricating an inverse opal. The DHF-PPV inverse opal maintained well-defined periodic structures of the silica opal template, showing ordered and well-packed spherical air-pores by scanning electron microscopy. The DHF-PPV inverse opal showed an optical stop band based on the periodic pattern of the refractive index in the visible wavelength region. A dip in the photoluminescence spectrum resulting from the influence of the stop band was observed.
