Zusammenfassung:	To provide a method for preparing an amphiphilic cyclodextrin polymer with a high specific surface area, and a use thereof.SOLUTION: A method of preparing an amphiphilic cyclodextrin porous polymer includes the steps of: grafting an aromatic compound to cyclodextrin; and crosslinking it with an alkylating agent under the condition where Lewis acid is used as a catalyst. A BET specific surface area of the amphiphilic cyclodextrin porous polymer calculated from an adsorption/desorption isotherm with a nitrogen gas is 1200 m2 g-1 or more.SELECTED DRAWING: Figure 2 【課題】高い比表面積を有する両親媒性シクロデキストリンポリマーを調製するための方法およびその使用の提供。【解決手段】芳香族化合物をシクロデキストリンにグラフトする工程と、触媒としてルイス酸を用いた条件下で、アルキル化剤により架橋する工程と、を有する両親媒性シクロデキストリン多孔質ポリマーの調製方法であって、前記両親媒性シクロデキストリン多孔質ポリマーの窒素ガスによる吸着脱離等温線から算出されたＢＥＴ比表面積は、１２００ｍ２ｇ-１以上であることを特徴とする調製方法。【選択図】図２
