Flexible Electrochromic Devices from Self-Assembled Organic Molecules

这个博士项目将专注于基于芳香族有机小分子的电致变色材料的合成和自组装。这些材料可用于在施加外部刺激（例如小电压、光或热）时可逆地将颜色从透明变为有色的装置中。这些材料可用于传感器、智能玻璃、光学设备等。该项目将涉及各种此类分子的合成和优化，以根据应用实现优选的颜色变化。需要对分子进行设计和优化，以调整颜色变化所需的条件。将进行分子的官能化以帮助小有机分子组装成聚集结构，其稳定电荷，从而导致颜色变化。一旦获得所需的颜色和刺激，这些材料将被加工成设备，以便使用。这将涉及使用不同的基底和涂层等，使得材料可以用于许多不同的可能应用。我们将特别专注于为智能玻璃以及可穿戴传感器制备涂层。

This PhD project will focus on the synthesis and self-assembly of electrochromic materials based on small aromatic organic molecules. These materials can be used in devices that reversibly change colour from transparent to coloured upon the application of an external stimulus, such as a small voltage, light or heat. Such materials can be used for sensors, smart glass, optical devices etc. The project will involve the synthesis and optimisation of a variety of such molecules for a preferred colour change depending on application. Design and optimisation of the molecules will be needed to tune the conditions needed for the colour change. Functionalisation of the molecules will be carried out to aid the assembly of the small organic molecules into the aggregated structures which stabilise the charge, resulting the colour change. Once the desired colour and stimulus needed has been achieved, the materials will be processed into devices so that they can be used. This will involve using different substrates and coatings etc. so that the materials can be used for the many different possible applications. We will specifically focus on preparing coatings for smart glass, as well as wearable sensors.
