In this study, we report poly(1H-thieno[3,4-d]imidazol-2(3H)-one) (pTIO) derivatives for an electrochromic (EC) type e-paper and its novel printing fabrication process. pTIO is a kind of conductive polymer (CP) s which are known as one of the EC materials. The electrochromism of pTIO is unique, because its color in doped state is almost transparent (pale gray). A transparent state is required t...

Prussian Blue nanoparticles were electrodeposited on transparent grapheme film, which showed a promising electrochromism with response times in the range of 3.3-38 s.

The manganese containing center of the oxygen evolving complex accumulates four oxidizing equivalents in the four stepped water oxidation cycle. Based on experiments on electrochromic absorption transients and the reduction rate of the primary electron donor, P680, it has been speculated that the oscillations of these variables reflect the net charge of the center as calculated from the differe...

Redox-driven mechanical movement, which has been achieved for a liquid-crystalline (LC) bistable [2]rotaxane in the LC phase, is accompanied by obvious electrochromism (electrochemically induced changes in color) of the material. The dumbbell-shaped LC [2]rotaxane with redox-active moieties, which interlocks with an ionic macrocycle, forms ordered redox-active condensed states.

Electrochromism has been demonstrated by three novel electrochemically-reversible compounds and, which were synthesised by Pd catalysed cross-coupling of iodotrimethylTTF (6) and 2,6(7)-diiodoTTF (7) with the 2,5-diaryl-1,3,4-oxadiazole derivatives 1 and 2 containing terminal ethyne and butadiyne groups.
