摘要

In an ultra-violet (UV)-protected electrochromic solution containing oxidizable substance(s), which yield electrons at an anode, and reducible substance(s), which accept electrons at a cathode, which are converted from weakly coloured or colourless forms to coloured forms, with an increase in the visible extinction, and revert when the charge is equalised, (a) at least one and are linked by a covalent bridge; and (b) the solution contains UV absorber(s) selected from optionally substituted cinnamic esters and optionally substituted 2-hydroxybenzophenones. The oxidizable and reducible substances of the type RED1 and OX2 respectively and are converted to the coloured forms OX1 and RED2. An Independent claim is also included for electrochromic devices containing the solution.
