Photochromism of indolino-benzopyrans studied by NMR and UV-visible spectroscopy
The synthesis of photochromic 3,3-di(4′-fluorophenyl)-3H-benzopyrans fused to an indole moiety is described. The structures of photomerocyanines elucidated by NMR spectroscopy and spectrokinetic data (λmax of colored form, colorability, and rate constant of bleaching) obtained by UV-visible spectro...
