Switchable Electrochromic Images Based on a Combined Top-Down Bottom-Up Approach

The preparation of switchable, high‐resolution (360 dpi) electrochromic pictures in sealed transparent and reflective cells is described. Viologens were inkjet printed, chemically amplified, and crosslinked on mesoporous TiO2 thick‐film electrodes (see Figure). As a counter electrode, e.g., opticall...

Zusammenfassung:The preparation of switchable, high‐resolution (360 dpi) electrochromic pictures in sealed transparent and reflective cells is described. Viologens were inkjet printed, chemically amplified, and crosslinked on mesoporous TiO2 thick‐film electrodes (see Figure). As a counter electrode, e.g., optically transparent and electrochemically fast CeO2 on mesoporous antimony tin oxide was used.
