Bi(III) insertion was performed in an NMR tube by mixing either 3o or 3i (3.0 µmol, 3.0 mg), DMSO-d6 (500 µL), DIPEA (17.2 µmol, 3 µL) and 200 µL of solution S2. Heating the NMR tubes at 85 °C for respectively 4 and 16 hours led quantitatively to 3o, A solution (S2) of Bi(NO3)3 (37.6 µmol, vol.18

, Note that the "in" and "out" labelling has been initially chosen with the strap in the broken-shape conformation when no X-ray structure of this series was yet available, see previous reference. We now know that most of these ligands adopt the W-shape conformation even without any coordination driving force

, It is worth to remind that typical graphic abaci have been calculated only in specific cases using the classical ring current incorporating two circular loops crossing the macrocyclic plane. In this type of graph, the iso-shielding lines indicating the incremental shift values (?, ppm) result from the plot of the out-of-plane coordinate (z, Å) against the radial distance from the center of the porphyrin (p, Å). For more details, see H. Scheer and, pp.399-524, 1975.
