    • From the spectral data it is not possible to gain information on the possible isomers, which can be formed in the biradical respect to the relative orientation of the radical arms both in the paraphenylene portions (pseudo-meta, o pseudo-para) and in the macrocycle (sin or anti). For a discussion on the possible isomers in disubstituted paracyclophanes see Ref. 12.

    • The formation of a self-complexing system having the radical inside the cavity cannot be proved by NMR because of the lack of the nitroxide heterocyclic signals in the spectrum.
