Electrochromic materials indicating reversible color change upon application of electrical stimuli are widely employed to electronic applications including displays. In this work, asymmetric (or symmetric) viologens were dissolved in ion-gels consisting of P(VDF-co-HFP) and [EMI][TFSI], which were applied to EC devices (ECDs). All ion gel-based ECDs showed characteristics of low-voltage operation and low-power consumption to maintain colored states. By utilizing different EC behaviors of two viologens and rubbery character of the gel, we successfully demonstrated voltage-tunable, multicolor, flexible ECDs on plastic. |
