Inkjet-printed polymer-based electrochromic and electrofluorochromic dual-mode displays
We report on inkjet-printed dual-mode devices based on the synchronous electrochromic and electrofluorochromic effect of the polyindenofluoren-8-tryarylamine polymer (PIF8-TAA). Reference devices show switching times under 4 s, a coloration efficiency of 542 ± 10 cm2 C−1 at 395 nm, an electrochromic...

| Summary: | We report on inkjet-printed dual-mode devices based on the synchronous electrochromic and electrofluorochromic effect of the polyindenofluoren-8-tryarylamine polymer (PIF8-TAA). Reference devices show switching times under 4 s, a coloration efficiency of 542 ± 10 cm2 C−1 at 395 nm, an electrochromic contrast of 50 ± 4% in the visible spectra and a fluorescence contrast ratio of 4.1 ± 0.3. The material is highly transparent in its neutral state and changes to a deep red color by oxidation. Utilizing PEDOT:PSS as electrode material, inkjet printing enabled the fabrication of freely, digitally designed device layouts providing a cost-efficient method for low-level display applications. The results highlight the applicability of digitally printed dual-mode EFCD for signage or advertisements. |
