  • Patent number: 7713545
    Abstract: Presents novel hollow fiber shaped organic nanotubes that can be easily produced in a short time span and also have a broad range of utility. An N-glycoside type glycolipid represented by the general formula (1) shown below. G-NHCO—R??(1) (In the formula, G represents a saccharide radical other than a hemiacetal hydroxyl group bonded to the anomer carbon atom of the saccharide, and R represents an unsaturated hydrocarbon group containing ten to 39 carbon atoms.) This molecule self-aggregates and forms hollow fiber shaped organic nanotubes in water when this N-glycoside type glycolipid is dissolved, allowed to cool gradually and allowed to stand undisturbed at room temperature. The average external diameter of the nanotubes is from 70 nm to 500 nm and the average internal diameter (average diameter of the cavity) is from 40 nm to 300 nm.

  • Publication number: 20060140847
    Abstract: The objective is to easily introduce a desired functional substance into organic nanotubes under milder conditions such as ambient temperature and ambient pressure. The method comprises the steps of allowing a surface active organic compound comprising hydrophobic hydrocarbon groups and hydrophilic groups to self aggregate in liquid phase to form organic nanotubes having an internal cavity size of at least 5 nm (step 1), freeze drying the organic nanotubes (step 2), dissolving or dispersing a desired functional substance in a solvent (step 3) and dispersing said freeze dried organic nanotubes in the solvent or the dispersion at or below the gel-liquid crystal phase transition temperature of said surface active organic compound (step 4). The organic nanotubes formed can be used in a variety of applications depending on the properties of the functional substance.
