Abstract

As newly designed electrochromic devices (ECDs), we fabricated a multi-patterned display (MPD) and a tube-shaped display (TSD) with Fe(II)-based metallo-supramolecular polymer (polyFe) and/or Ru(II)-based polymer (polyRu). The MPD was fabricated by staking three independent ECDs. The device thickness was less than 5 mm using both-sides-coated ITO glasses. The MPD presented eight different images with high contrast and fast response. The bleaching and coloring times (Tb and Tc) were 1.7 and 2.0 s at 500 nm, in which the absorption attributed to polyRu appears, respectively, and 3.6 and 1.8 s at 600 nm, in which the absorption attributed to polyFe appears, respectively. The TSD was successfully fabricated using two flexible ITO-PET films and two tube-shaped glasses. The TSD also showed good electrochromic behavior (Tb: 22 s and Tc: 3.6 s). These results guarantee the achievement of the further application for new design of architecture or appliance.
