Abstract
Picket porphyrins delivering oxygen donor atoms borne by aromatic cycles around the sphere of coordination of bismuth cation have been studied for their ability to complex bismuth in a period of time not exceeding an hour. For this investigation, various structural features were considered: steric strength and length of the link between the aromatic cycle and the macrocyle core, nature and location of the oxygen atom(s) on the aromatic cycle.
