The synthesis of the smaller analogues of the well-known [2.2.2]p,p,p-cyclophane (1) π-prismand were performed ia a well-established pyrolysis route from the corresponding disulfones. In spite of their smaller size and increased rigidity, these cyclophanes showed remarkably similar complexation behaviour with Ag+ ions compared to [2.2.2]p,p,p-cyclophane. X-Ray crystal structure determinations showed
