Development of pH-Sensitive Spin-crossover Iron(II) Complex Films, [FeII(diAMsar)]–Nafion: Manipulation of the Spin State by Proton Concentration

Development of pH-Sensitive Spin-crossover Iron(II) Complex Films, [FeII(diAMsar)]–Nafion: Manipulation of the Spin State by Proton Concentration

We newly synthesized transparent films composed of pH-sensitive spin-crossover complex [FeII(diAMsar)] (diAMsar: 1,8-diaminosarcophagine) and an ion-exchange polymer, Nafion, having different colors corresponding to proton concentration. The UV–vis spectroscopic measurements revealed that the films,...

Zusammenfassung:We newly synthesized transparent films composed of pH-sensitive spin-crossover complex [FeII(diAMsar)] (diAMsar: 1,8-diaminosarcophagine) and an ion-exchange polymer, Nafion, having different colors corresponding to proton concentration. The UV–vis spectroscopic measurements revealed that the films, which were provided under pH 4, 7, and 10 conditions, showed the spin state depending on pH.
