Abstract Carotenoids – prominent antioxidants (= electron donors) – are commonly not recognized as electron acceptors. Nonetheless, carotenoids can take up electrons under mild chemical conditions: dioxocarotenoids in alkaline DMSO and DMF form stable deeply colored carotenoid dianions, which react with different additives to new carotenoid derivatives.
