摘要

首次成功展示了一种新型的一体化电致变色装置，其材料为基于病毒的 Cu-MOF。将紫胶基 Cu-MOF 分散在光化学共晶溶剂中，直接用作电致变色材料，具有在宽范围可见光下具有良好调制能力的突出优点。在电位从 0 V 到 -3.5 V 的变化过程中，电致变色器件（ECD）的颜色从透明的淡绿变为蓝色。在关闭电源的 1.79 小时内，ECD 的透光率衰减不到 10%，这证明了 ECD 的双稳态性。这表明，ECD 可以在没有持续供电的情况下长时间保持其光学状态。

All-in-one electrochromic device from viologen-based Cu-MOF and photocurable eutectogel

A novel all-in-one electrochromic device from viologen-based Cu-MOF was demonstrated successfully for the first time. The viologen-based Cu-MOF was dispersed in a photochemical eutectic solvent and directly used as an electrochromic material with the outstanding advantage of good modulation ability in a wide range of visible light. The electrochromic device's (ECD) color changed from transparent and light lime green to blue during the change of potential from 0 V to −3.5 V. The bistability of the ECD was demonstrated by the transmittance degradation of less than 10 % over 1.79 h when the power was turned off. This showed that the ECD could maintain its optical state long without a continuous power supply.
