| Research Abstract |
Salcomine (N,N'-disalicylidenethylenediaminocobalt)is the oldest known and the simplest example of oxygen-binding complexes. Salcomine micro-crystals homogeneously dispersed and supported in a polymer such as poly (methacrylate) not only worked as a reversible and specific oxygen-adsorbent under air at room temperature but discontinuously bound oxygen at the atmospheric oxygen partial pressure of ca. 15cmHg to give an on-off-like oxygen- binding curve. This specific oxygen-binding profile was analyzed with the equation for a cooperative effect, and was described with both a crystal structure change of salcomine and an interaction of salcomine with the surrounding polymer. The salcomine/polymer film reversibly bended or expanded and shrinked in response to the atmospheric oxygen pressure. This oxygen-responding streching of the film was ascribed to also the structure change of salcomine. A composite of salcomine with carbon powder was also prepared. The salcomine composite was heated up under 6V-application, and released bound oxygen repeatedly in response to the voltage on-off application.
