Organic ruthenium complexes and polymers with electrochromic activity in the near infrared region were prepared and their electrochemical and optical properties were investigated. The intrinsic attenuating property of these materials depends mainly on the concentration of the pair of ruthenium units in the complexes or polymers. One cured film had the attenuating power of 6.9 dB per micron thic...

Flexible displays are attracting considerable attention as a visual interface for applications such as in electronic papers and paper electronics. Passive or active matrix addressing of individual pixels require display elements that include proper signal addressability, which is typically provided by non-linear device characteristics or by incorporating transistors into each pixel. Including s...

In this report the design, fabrication, and testing of inkjet-printed electrochromic pixels (ECPs) incorporating biochrome, xanthommatin (Xa) as programmable display units is described. As a redox sensitive chromophore, Xa present in some species physiological indicator with red (reduced) or yellow (oxidized) colors associated different behavioral developmental stages. These features have been ...
