Description:
<jats:title>Abstract</jats:title><jats:p>A new series of channel‐type molecules presenting the features of potential transmembrane structures is described. They result from the grafting of amphiphilic side chains on a β‐cyclodextrin derivative <jats:bold>3</jats:bold> that constitutes the organizing core. They belong to the ‘bouquet’ family (<jats:italic>B</jats:italic>). Compounds bearing poly(oxyethylene) side chains, <jats:italic>B</jats:italic><jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="graphic/tex2gif-stack-1.gif" xlink:title="urn:x-wiley:0018019X:media:HLCA19920750315:tex2gif-stack-1" /><jats:bold>16</jats:bold> and <jats:bold>17</jats:bold>, and their polymethylene analogues <jats:italic>B</jats:italic><jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="graphic/tex2gif-stack-2.gif" xlink:title="urn:x-wiley:0018019X:media:HLCA19920750315:tex2gif-stack-2" /><jats:bold>18</jats:bold> and <jats:bold>19</jats:bold>, were synthesized. The properties investigated emphasize the suitability of such molecules to be incorporated into lipid bilayer membranes.</jats:p>
