It has been pointed out (Pergamon, New York) that the coat of arms of the Ciba Foundation displays a [5]catenane with its rings portrayed slightly differently than the symbol of the International Olympics. It is noted that although “neither of these concatenated emblems has chemical significance”… “both symbols promote universal brotherhood among the five continents the former in athletics and the latter in education and knowledge.”

A single macrocyclization afforded a series of catenanes containing three, four, five, six, and seven rings, in which one large ring was encircled by two, three, four, five and six small rings, respectively. The structure of these catenanes is different from the linear ones described in this communication. See

The low solubility of 1 in acetonitrile makes the self‐assembly procedure leading to the [3]catenane difficult to perform in an efficient manner.

6 was carried out on a Kratos MS80RF mass spectrometer (accelerating voltage, 3 kV; resolution, 1000) coupled to a DS90 data system and off‐line Sun Workstation for processing the raw data experiments. The atom gun was an adapted saddle‐field source (Ion Tech Limited) operated at ca. 8 keV and a tube current of ca. 2 mA. Krypton was used to provide a primary beam of atoms, and the samples were dissolved in a small volume of 3‐nitrobenzyl alcohol which had previously been coated onto a stainless steel probe tip. Spectra were recorded in the positive‐ion mode at a scan speed of 30 s per decade.

V; resolution, 1000) coupled to a Sun Spare Station with Mach3 software. The samples were dissolved in acetone, and a small volume (1–2 μL) was added to the 3‐nitrobenzyl alcohol matrix. Spectra were recorded in the positive‐ion mode at a scan speed of 5 s per decade. We gratefully acknowledge the assistance of Kratos Analytical, and in particular Dr. M. Kimber, Dr. H. Wight, and Dr. J. Moncur, in the collection of the mass spectra for these compounds.
