The simplicity of light-emitting electrochemical cells (LECs) offers the potential ability for printed electronics. However, the designs of current LECs are limited and require fine control of the active/metal layers, which hampers their applicability. Here, we propose a versatile LEC structure that is easily prepared by laminating plastic films and drop-casting organic solutions. This simple fabrication allows us to realize various colored LECs with arbitrarily patterned light-emitting shapes. Moreover, the proposed structure is advantageous for building LECs using a solution-based process because of the absence of severe material/metal patterning. Thus, it presents a new approach for developing flexible printed devices.

一种用于印刷电子产品的发光电化学电池的多功能结构

发光电化学电池 (LEC) 的简单性为印刷电子产品提供了潜在的能力。然而，当前 LEC 的设计是有限的，需要对活性/金属层进行精细控制，这阻碍了它们的适用性。在这里，我们提出了一种多功能的 LEC 结构，可以通过层压塑料薄膜和滴铸有机溶液轻松制备。这种简单的制造使我们能够实现具有任意图案发光形状的各种彩色 LEC。此外，由于没有严重的材料/金属图案化，所提出的结构有利于使用基于溶液的工艺构建 LEC。因此，它提出了一种开发柔性印刷设备的新方法。
