Summary of the % radiochemical yields (RCY%) of the [52Mn]Mn-porphyrins.

A) Graphs showing a comparison of the radiochemical yields achieved overtime for the microwave synthesis method (solid lines) compared to that achieved with labelling at 70 °C (dotted lines) for porphyrins 1–6. For porphyrin 3 a further comparison is shown with the MW method at 0.7 mM compared to 0.6 mM used in all other experiments. B) Direct comparison between the radiochemical yields achieved for porphyrins 1–6 after 1 h heating at 70 °C (chequered bars) versus the microwave method (solid colour bars). Additionally, the graph also highlights the large differences in radiolabelling with porphyrins 1–6 after 1 h heating at 70 °C. Error bars represent mean ± SD.
