    • 1 symmetry determined by calculations wouldimply the presence of four NH signals and four AB systems, when all the internal rotation is frozen. For the biphenyl systems, however, two barriers must be considered, the steric and the π-barrier. The slowing of only the steric barrier could give a degree of conformational freedom to the macrocycle and would account for the observed spectrum at -105 °C. Unfortunately, the solubility of compound 15 dramatically decreased at lower temperatures
