摘要
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.
