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.

功能材料可在中性离子和自由基离子之间通过电化学方式切换颜色（开/关） 需要状态并能够显示大量颜色以满足商业应用的需求。能够进行这种颜色切换的材料已在隐形技术中得到应用， 迷彩材料、纺织品、无窗帘窗户、价格显示标志、天窗、电子显示器（即苹果手机）、太阳镜和电信交换机等等。 尽管目前许多应用都使用电致变色材料，但这些材料的制备 电化学诱导变色化合物并不简单。我们开发了一系列 可以轻松制备的新型化合物，没有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装置。一个 将使用我们的材料作为电致变色材料来制造透射和柔性电致变色器件 层。这将作为验证我们的材料适用性的概念验证 电致变色器件。
