PROBLEM TO BE SOLVED: To provide an asymmetric organic nanotube that can be produced in large quantities at low cost, and makes it possible to encapsulate various kinds of guests.SOLUTION: Asymmetric two-headed lipid molecules represented by the general formula 1 are made to assemble in liquid by themselves, to obtain an asymmetric organic nanotube. In general formula 1: X-NH-(CH2)m-CONH-(CH2)n-CO-Y, m and n are an integer of 5-11, X is an optically active polyhydroxy alkanoyl group, Y is an OH group, a C1-3 alkoxyl group, and the like.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】安価で大量に製造でき、様々な種類のゲストをカプセル化できる非対称有機ナノチューブを提供する。【解決手段】下記一般式１で表わされる非対称双頭型脂質分子を液体中で自己集合させて、非対称有機ナノチューブを得る。 一般式１ Ｘ―ＮＨ―(ＣＨ２)ｍ―ＣＯＮＨ―(ＣＨ２)ｎ―ＣＯ―Ｙ ここで、ｍおよびｎが５～１１の整数であり、Ｘが光学活性なポリヒドロキシアルカノイル基であり、ＹがＯＨ基または炭素数が１～３のアルコキシル基等である。【選択図】図１
