  • Patent number: 9970749
    Abstract: Provided are: a sheet of colloidal crystals immobilized in resin exhibiting intense structural color, enabled to be observed easily from a squarely facing direction against a surface; and use thereof. The sheet of the present invention, assuming a direction perpendicular to part of a surface of a target area including partially the sheet surface is set as a specified axis, satisfies: (1) The target area includes plural inclined back-reflecting crystal-domains crystal domains having colloid particles immobilized in resin and including crystal lattice planes capable of Bragg-back reflecting at least some of components in a visible wavelength range of incident light having greater than 0 incident angle with the specified axis; and (2) By defining an azimuth angle around the specified axis, the inclined back-reflecting crystal-domains are so oriented that intensity of reflected light caused by Bragg back reflection varies depending on the azimuth angle of the incident light.

  • Patent number: 9970850
    Abstract: A sheet of colloidal crystals immobilized in resin exhibiting intense structural color and allowing easy observation thereof from squarely facing direction against the surface; and application thereof are provided. The sheet includes crystal domains comprising colloidal crystals immobilized in resin. The Bragg reflection intensity resulting from crystal domains according to back reflection spectrum measurement to the sheet surface satisfies the following conditions (1) and (2). (1) When elevation angle from the sheet surface is in a range of at least 60° and less than 90° and measurement is performed at a predetermined azimuth angle on the sheet surface, intensity is not 0 and (2) when elevation angle from the sheet surface is in the range of at least 60° and less than 90° and azimuth dependency on the sheet surface is measured, the intensity exhibits a maximum value at the predetermined azimuth angle.

  • Publication number: 20070172600
    Abstract: External energy is fed to N-[3-{3,5-bis{3,5-bis[3,5-bis(4-mercaptobenzylthio)benzylthio]benzylthio}benzyloxy}-propionyl-4-nitro-1-naphthylamine (18a) being a molecule capable of photosensitization as an intermediate excitation medium, fixed on support (12) of a metal, so as to photosensitized molecule of excited triplet state (18b), thereby inducing an excited triplet energy transfer from this photosensitized molecule to first molecule (28a) having a residue capable of bonding. The first molecule (28b) having thus been excited by the excited triplet energy transfer is bonded with second molecule (30) having a residue capable of bonding which is a bonding object to be bonded with the first molecule.
