In this study, we propose low power consumption, all-in-one type electrochromic devices (ECDs) for effective heat shutters. Considering diffusion-controlled device operation, polymeric viologens (poly-viologens) are synthesized to lower the diffusivity of EC chromophores and to minimize self-bleaching. In comparison with devices based on mono-viologens corresponding to the monomer of poly-viologens, poly-viologen-containing ECDs exhibit advantages of lower coloration voltage (ca, -0.55 V) and higher coloration/bleaching cyclic stability (>1500 cycles). In particular, poly-viologen ECDs show remarkably reduced self-bleaching as designed, resulting in extremely low power consumption (~8.3μW/cm2) to maintain the colored state. Moreover, we successfully demonstrate solar heat shutters that suppress the increment of indoor temperature by taking the advantage of low-power operation and near-IR absorption of the colored poly-viologen-based ECDs. Overall, these results imply that the control of the diffusivity of EC chromophores is an effective methodol. for achieving single-layered, low-power electrochem. heat shutters that can save indoor cooling energy when applied as smart windows for buildings or vehicles.1,4-Bis(bromomethyl)benzene(cas: 623-24-5Category: bromides-buliding-blocks) was used in this study.
1,4-Bis(bromomethyl)benzene(cas: 623-24-5) belongs to organobromine compounds.Organobromine chemicals are produced naturally by an array of biological and other chemical processes in our environment. Some of these compounds are identical to man-made organobromine compounds, such as methyl bromide, bromoform, and bromophenols, but many others are entirely new moleclar entities, often possessing extraordinary and important biological properties.
