viologen
/vʌɪˈəʊlədʒ(ə)n
/noun Chemistry
Any of a series of synthetic compounds related to the weedkiller paraquat, used as redox indicators. They contain heteroaromatic cations of the general formula (C5H4NR)22+.The intermolecular interactions between the viologens and the macrocyclic molecule were investigated in a solution before photoirradiation....
- Methyl viologen also affects electron-transducing reactions in the endoplasmic reticulum and in mitochondria.
- The transgenic plants were also more tolerant to the oxidative damage caused by methyl viologen showing less chlorosis and less electrolyte leakage than the controls.
Origin
1930s: from violet (because of the purple colour when electrochemically reduced) + -gen.
