摘要:

Magnetic and photochromic behaviors of cobalt-iron polycyanide (Na0.34Co1.33Fe(CN)6·4.5H2O) were investigated. This compound changes its spin state via photo-induced charge transfer between a low spin state of FeII(S= 0)-CN-CoIII(S= 0) and a high spin state of FeIII(S= 1/2)-CN-CoII(S= 3/2). The spin transition is accompanied by a color change, indicating a potential application for novel photochromic material.
