| Research Abstract |
We aimed at the construction of self-oscillating metal complex system that is composed of spin crossover complexes with acid/base function and self-oscillating pH solution found by Epstein and co-workers. They have found that a mixture of methyleneglycol, sulfite, gluconolactone (MGSM) demonstrates pH oscillation from ~7.0 to ~9.4 induced by the dehydration of methyleneglycol accompanied by an autocatalytic production of OH- together with the catalyzed hydrolysis of gluconolactone. We tried to combine the MGSM pH oscillator with spin crossover iron complexes with benzimidazole pyridine and a tripod-type polydentate ligands, respectively, that demonstrate low-spin/high spin conversion responding to pH. This paper will demonstrate the detalied experimental results of the combined system toward the fabrication of self-oscillating metal complex as a new bistable molecular system.
