分子或超分子系统能够电和光刺激的颜色变化仍然是罕见的。我们提出了一种基于静电复合物的纳米级聚氧乙烯簇和一个静电场的器件设计。该涂层通过光和/或电诱导刺激可逆地改变色前透明为蓝色。这些组分的选择可在整个可见光范围内实现完美的透明度、大的光学响应、可逆操作和出色的稳定性。
Molecular or supramolecular systems capable of electro- and photostimulated color changes are still rare. We present a device design based on an electrostatic complex of a nanoscopic polyoxometalate cluster and a polyelectrolyte. The coating reversibly chances color front transparent to blue by photo- and/or electroinduced stimulation. The choice of the components results in perfect transparency over the entire visible range, a large optical response, reversible operation, and excellent stability.
