Red-hair-inspired chromogenic system based on a proton-switched dehydrogenative free-radical coupling

In the presence of micromolar peroxides or biometals (Fe(III), Cu(II), V(V) salts), and following a strong acid input, the stable 3-phenyl-2H-1,4- benzothiazine is efficiently converted to a green-blue Δ 2,2′-bi(2H-1,4-benzothiazine) chromophor
