Abstract

We report here an unprecedented utility of redox-active transition-metal complexes as heat-shielding materials. A poly-(vinyl alcohol) film containing mixed-valent cluster [Ru 3-(μ 3-O)(μ-CH 3CO 2) 6(mbpy +) 3](PF 6) 3 (1) (mbpy + = 1-methyl-4,4′- bipyridinium cation), which strongly absorbs light in the near-infrared region, shows heat-shielding characteristics whose efficiency is found to highly depend on the redox state of the cluster dye.
