Abstract
The polymer-supported N,N'-di(salicylidene)ethylenediaminatocobalt(II) [Co( salen)] took up oxygen through 2/1 Co/dioxygen adduct formation. The compos ite film of the polymer-supported [Co(salen)] and polymer layers reversibly bent under an oxygen and nitrogen atmosphere. The stretching was caused by a structural change in the [Co(salen)] crystal before and after the oxygen -binding, which was analyzed based on the near-IR spectral and density chan ge as well as EXAFS.
