| abstract |
A dioxygen-binding complex of the 'picnic-basket' porphyrin type. The complex includes a phenylporphyrin structure, a metal M bound to the phenylporphyrin structure, where M is iron or cobalt, a strap structure attached to the phenylporphyrin structure and comprising a bridge linkage Y, where Y is X, X-CH2, or CH2-X-CH2, where X is O, S, S(=O), S(=O)2, NR, or +NRR', and R and R' are the same or different and are a hydrogen or a lower alkane, and a neutral, sigma-donating ligand, L, which binds to the metal on the open side of the phenylporphyrin structure. Use of the complex for extracting oxygen from a fluid and as a component in an oxygen sensor is also disclosed. |
