2,5-Bis(3,5-di-tert-butyl-4-oxo-2,5-cyclohexadien-1-ylidene)-2,5-dihydrothiazole, which is to our knowledge, the first p-terphenoquinone incorporating a 1,3-thiazole ring, had a sharp and strong absorption in the visible region and good electron affinity enhanced by sp2 nitrogen atom. Alkali-metal reduction afforded the corresponding dianion, which showed strong fluorescence.
