Abstract
(DE)
Das neue elektrochrome System enthaltend mindestens eine oxidierbare Substanz RED1 und mindestens eine reduzierbare Substanz OX2, die jeweils unter Zunahme der Extinktion im sichtbaren Bereich des Spektrums von einer schwach gefärbten oder farblosen Form in eine gefärbte Form übergeht, ist dadurch gekennzeichnet, daß die wechselseitige Umwandlung von oxidierter und reduzierbarer Form durch Bruch bzw. Bildung einer $g(s)-Bindung erfolgt.
(EN)
The electrochromic system proposed contains at least one oxidizable substance RED1 and at least one reducible substance OX2 each of which changes from a colourless or only slightly coloured form into a coloured form by virtue of an increase in the absorbance in the visible region of the spectrum. The system is characterized in that the conversion of the oxidizable form into the reducible form and vice versa occurs by cleavage or formation of a $g(s)-bond.
(FR)
L'invention concerne un nouveau système électrochrome qui contient au moins une substance oxydable RED1 et au moins une substance réductible OX2 qui passent chacune, sous l'effet de l'augmentation de l'absorbance dans la zone visible du spectre, d'une forme faiblement colorée ou non colorée à une forme colorée. Ce système se caractérise en ce que la conversion réciproque de la forme oxydée et de la forme réductible intervient par rupture ou formation d'une liaison $g(s).
