Abstract
The invention provides a novel hollow fibrous organic nanotube comprising an O-glycoside type glycolipid having an aldose residue as the glycosyl group and a group represented by the general formula: wherein R is an unsaturated straight-chain hydrocarbon group having 12 to 18 carbon atoms, as the aglycon. The nanotube structure can be obtained by gradually cooling a saturated aqueous solution of the starting material down to room temperature where the solution is kept standing for days or for weeks to cause spontaneous formation of hollow tubes as precipitates.
