Functional materials with electrochemically switchable colors between their neutral and radical ion (on/off) states and capable of displaying a large palette of colours are required to meet the demands of commercial applications. Materials capable of such color switching have found uses in stealth technology, camouflage materials, textiles, curtainless windows, pricing display signs, sun roofs, electronic displays (i.e. i-phone), sunglasses, and telecommunications switches, to name but a few. Despite the many current applications using electrochromic materials, the preparation of these electrochemically induced color changing compounds is not straightforward. We have developed a series of novel compounds that can be easily prepared without the drawbacks of materials currently used in electrochromic displays. An electrochromic prototype device is proposed based on our new materials. A transmissive and flexible electrochromic device will be fabricated using our materials as the electrochromic layer. This will serve as a proof-of-concept for validating the suitability of our materials for use in electrochromic devices.

具有可在中性离子和自由基离子(开/关)之间电化学切换颜色的功能材料 为了满足商业应用的需求，需要国家和能够显示大的调色板。能够进行这种颜色切换的材料已经在隐形技术中得到了应用， 伪装材料、纺织品、无窗帘窗户、定价展示牌、遮阳顶、电子显示屏(即i-phone)、太阳镜和电信开关，仅举几例。 尽管目前使用电致变色材料的应用很多，但这些材料的制备 电化学诱导的颜色变化并不是一帆风顺的。我们已经开发了一系列 新型化合物，可以很容易地制备，而不存在目前使用的材料的缺点 电致变色显示器。基于我们的新材料，提出了一种电致变色原型器件。一个 利用我们的材料作为电致变色材料，可以制作出透射性和柔性的电致变色器件 一层。这将作为一种概念验证，以验证我们的材料是否适合用于 电致变色器件。
