“…Both NMR and GPC tests failed because of the ferromagnetic nature of Fe(II) and Ru(II) and broken coordination bonds in the column, respectively. One can only confirm that the polymer length of solid state Fe-MEPE is very long and more than 1 μm from AFM measurements . Despite lacking direct evidence of molecular structural differences, the smaller potential shifts in the CV results clearly indicate that interactions between the central Ru and Fe ions in the pristine Fe-MEPE/Ru-MEPE are weaker than those in the hybrid Fe/Ru-MEPE.…”

“…One can only confirm that the polymer length of solid state Fe-MEPE is very long and more than 1 μm from AFM measurements. 51 Despite lacking direct evidence of molecular structural differences, the smaller potential shifts in the CV results clearly indicate that interactions between the central Ru and Fe ions in the pristine Fe-MEPE/Ru-MEPE are weaker than those in the hybrid Fe/Ru-MEPE. Because the color mixing is achieved physically by stacking ink drops instead of metal-alternating chemical synthesis, this interaction between metal ions is intermolecular rather than intramolecular.…”

In this study, electrochemical responses of inkjet-printed multicolored electrochromic devices (ECD) were studied to evaluate the feasibility of presenting multiple colors in one ECD. Metallo-supramolecular polymers (MEPE) solutions with two primary colors were inkjet-printed on flexible electrodes. By digitally controlling print dosages of each species, the colors of the printed EC thin film patterns can be adjusted directly without premixing or synthesizing new materials. The printed EC thin films were then laminated with a solid transparent thin film electrolyte and a transparent conductive thin film to form an ECD. After applying a dc voltage, the printed ECDs exhibited great contrast with a transmittance change (ΔT) of 40.1% and a high coloration efficiency of 445 cm(2) C(-1) within a short darkening time of 2 s. The flexible ECDs also showed the same darkening time of 2 s and still had a high ΔT of 30.1% under bending condition. This study demonstrated the feasibility to fabricate display devices with different color setups by an all-solution process and can be further extended to other types of displays.
