研究目的
The main goal of this study is the demonstration and application of the coupling of charge storage-release with electrochromism in nanoscale bilayers. The feasibility of electrochromic charge-storage devices is shown for the first time by the inclusion of a gel-type structure in this manuscript. One unique feature is the possibility to operate the charged materials in an orthogonal manner as electrochromic devices.
研究成果
The demonstrated molecule-based bilayer can efficiently store and release electrical charge with concurrent color-to-color and color-to-colorless transitions. Matching the redox-properties of the two nanoscale layers by only varying the central metal cation (i.e., ruthenium and iron) afforded a unique thin film set-up that is operated by applying different potentials. The metal cation, the deposition sequence, and the thickness of the gate are essential elements for the functioning of the bilayer.
研究不足
The charge remains in a trapped state at -0.8 V, even though the total potential drop in the gate is 2.6 x 104 V/cm. These observations show that the bilayer can be used in an orthogonal manner as an electrochromic material while charge remained trapped.
