Dynamic host and guest interaction for sustainable electrochromic display

A method of making an electrochromic device, the method comprising:

• positioning an electrochromic layer over a first electrode, wherein the electrochromic layer comprises an electrolyte, a host unit, and a guest unit;
• positioning an ion conducting layer over the electrochromic layer;
• positioning an ion storage layer over the ion conducting layer;
• and
• positioning a second electrode over the ion storage layer,
• wherein the host unit and guest unit are configured to form a host-guest complex upon a first reduction or oxidation stimulation to the host unit or the guest unit and wherein the host-guest complex is configured to reversibly dissociate to the host unit and the guest unit upon a second oxidation or reduction stimulation to the host-guest complex.

A method comprising:

• providing an electrochromic device, the electrochromic device comprising:
• a first electrode;
• an electrochromic layer over the first electrode, wherein the electrochromic layer comprises an electrolyte, a host unit, and a guest unit;
• an ion conducting layer over the electrochromic layer;
• an ion storage layer over the ion conducting layer;
• and a second electrode over the ion storage layer,
• wherein the host unit and guest unit are configured to form a host-guest complex upon a first reduction or oxidation stimulation to the host unit or the guest unit and wherein the host-guest complex is configured to reversibly dissociate to the host unit and the guest unit upon a second oxidation or reduction stimulation to the host-guest complex;
• applying a first voltage between the first electrode and the second electrode corresponding to a first reduction or oxidation stimulation;
• and
• applying a second voltage between the first electrode and the second electrode corresponding to a second reduction or oxidation stimulation.
