摘要：

Base-catalysed reactions of calix[4]crown-6 with suitable ditosylates produced unsymmetrical calix[4]-bis-crowns-6 1 and 2. Cesium ion preferred to bind the polyether loop substituted by 1,2-phenylene or 2,3-naphthylene groups as evidenced by X-ray structure. (C) 1998 Elsevier Science Ltd. All rights reserved.
