First Claim
Patent Images
1. A method for the manufacture of an electrochromic system using a nanoporous-nanocrystalline film comprising a semiconducting metallic oxide having a redox chromophore adsorbed thereto, wherein the redox chromophore comprises a compound of the formula wherein X is a charge balancing ion, the method comprising the steps of:
- (a) providing an electrochromic system comprising a first and a second electrode; and
(b) disposing said nanoporous-nanocrystalline film on said first or second electrode.
