In this article we demonstrate that a migration of iodine species and chemical transformation in a moist environment induced by a voltage-biased Pt electrode is able to alter the color and degree of charge transfer in a layer of the 2D organic molecular metal (BEDO-TTF)_2.4I₃ [BEDO = bis(ethylenedioxy)tetrathiafulvalene] self-assembled at the surface of a polycarbonate film. These effects produce a reversible electrochromic behavior of the layer with low operating voltages and fast operation times. Adjuvant with electrochromism, this flexible material exhibits rectifying behavior whose I-V curves are dependent on the voltage sweep directions. These results open new possibilities for the design and fabrication of organic flexible materials for soft electrochromic and rectifying components. The easy working principle ensures reliability, low power consumption, and versatility through its implementation into simple devices. Such working principle has been confirmed by temperature dependent resistance measurements, X-Ray, EDX-SEM, and conducting-AFM studies.

在本文中，我们证明了由偏压的Pt电极在潮湿环境中引起的碘类迁移和化学转化能够改变2D有机分子金属（BEDO-TTF）层的颜色和电荷转移程度）_2.4我₃[BEDO ＝双（亚乙基二氧基）四硫富瓦烯]在聚碳酸酯膜的表面上自组装。这些效应在低工作电压和快速工作时间的情况下产生了可逆的电致变色行为。具有电致变色作用的辅助材料，这种柔性材料表现出整流行为，其IV曲线取决于电压扫描方向。这些结果为用于软电致变色和整流组件的有机柔性材料的设计和制造开辟了新的可能性。简单的工作原理通过将其实施到简单的设备中，可确保可靠性，低功耗和多功能性。这种工作原理已通过与温度有关的电阻测量，X射线，EDX-SEM和导电AFM研究得到了证实。
