abstract The synthesis of new photochromic 2,2-di(4'-fluoro-phenyl)-2H-1-benzopyrans fused to an indole moiety is described. Spectrokinetic data (lambda(max) of colored form, colorability and rate constant of bleaching) obtained by UV-Visible spectroscopy and the structure of photomerocyanines elucidated by NMR spectroscopy, are reported.
