A compound for electrochromic devices. One such compound of the invention is dihydro-disubstituted phenazine (VI): wherein Ris and n=1-10.

Electrochromic compound

A compound for use in electrochromic devices.  The compound includes (1) &#x3b2;-(10-phenothiazyl)propoxy phosphonic acid; (2) &#x3b2;-(10-phenothiazyl)propyl-phosphonic acid; and (3) &#x3b2;-(10-phenothiazyl)propionate phosphonic acid.

This invention concerns an electochromic device comprising an electrode including a nanostructured metal oxide film, doped to metallic levels of conductivity and optionally modified by chemisorption of an electroactive compound. Such an electrochromic device is suitable for applications where optical modulation is required, such as large area static displays and automatically dimmable rear-view mirrors. The invention also concerns conducting nanostructured metal oxide films and electrodes comprising same and which are suitable for use in the electrochromic device.

Electrochromic device

An electrochromic system having a first electrode disposed on a transparent or translucent substrate, a second electrode, an electrolyte, an electron donor in solution in the electrolyte, and a nanoporous-nanocrystalline film. The nanoporous-nanocrystalline film has a semiconducting metallic oxide with a redox chromophore adsorbed thereto, intermediate the first and second electrodes.

Electrochromic system

A method for the manufacture of an electrochromic system using a nanoporus-nanocrystalline film comprising a semiconducting metallic oxide having a redox chromophore adsorbed thereto.

An electrochromic system having a first electrode disposed on a transparent or translucent substrate and a second electrode, an electrolyte, an electron donor and a nanoporous-nanocrystalline film of a semiconducting metallic oxide having a redox chromophore adsorbed thereto being intermediate the first and second electrodes. Such a system has a very rapid electrochromic effect.
