The article describes novel electrochromic materials (ECMs) that are based on a monolayer consisting of two or three isostructural metal complexes of 4'-(pyridin-4-yl)-2,2':6',2''-terpyridine simultaneously deposited on surface-enhanced support. The support was made by screen printing of indium tin oxide (ITO) nanoparticles on ITO-glass and has a surface area sufficient for a monolayer to give color visible to the naked eye. The ability to separately electrochemically address the oxidation state of the metal centers on the surface (i.e., Co/Co, Os/Os, and Fe/Fe) provides an opportunity to achieve several distinct color-to-color transitions, thus opening the door for constructing monolayer-based multicolor ECMs.
本文描述了一种新型电致变色材料（ECM），其基于由4'-(吡啶-4-基)-2,2':6',2''-三联吡啶的两种或三种同构金属配合物组成的单层，该单层同时沉积在表面增强载体上。该载体通过在ITO玻璃上丝网印刷氧化铟锡（ITO）纳米颗粒制成，其表面积足以使单层呈现肉眼可见的颜色。能够分别以电化学方式处理表面上金属中心的氧化态（即Co/Co、Os/Os和Fe/Fe），为实现几种不同的颜色到颜色的转变提供了机会，从而为构建基于单层的多色电致变色材料打开了大门。
