在本文中，我们报告了一种电化学策略，该策略可以以精确和简便的方式控制聚集诱导发射（AIE）分子在图案化电极上的位置，产生具有各种颜色的光致发光和电致发光图案。在电氧化过程中，由电活性表面活性剂组成的胶束被破坏，其中这些胶束中的AIE分子被释放到图案化电极上。这些图案化的电极不仅由金属，但也多种导电聚合物（CP）的预处理。一项深入的研究澄清了用作电极的CP的种类与由于CP的不同催化性能而导致的电活性表面活性剂的氧化速率之间的相关性。结合双极电化学的无线和梯度特性，很容易实现梯度发光模式。目前的研究表明，使用AIE发光体的更丰富的发光图案，可以通过这样的电化学方法开发的图形形状和发射颜色。
Herein, we report an electrochemical strategy that could control the location of aggregation‐induced emission (AIE) molecules on patterned electrodes in a precise and facile way, producing photoluminescent and electrochemiluminescent patterns with a variety of colors. A micelle composed of electroactive surfactants was broken during the electrooxidation process, in which AIE molecules inside these micelles were released on patterned electrodes. These patterned electrodes were pretreated by not only metal, but also multifarious conducting polymers (CPs). An in‐depth investigation clarified a correlation between the variety of CPs used as electrodes and the oxidation rate of the electroactive surfactant due to different catalytic performances of CPs. Furthermore, combined with wireless and gradient features of bipolar electrochemistry, a gradient luminescent pattern was easily achieved. The current studies suggest more abundant luminescent patterns using AIE luminophores can be developed by such an electrochemical method, in both of graphical shapes and emitting colors.
