Photochromic properties of new benzoindene-fused 2H-chromenes

Martins, Cristina I.,Coelho, Paulo J.,Carvalho, Luis M.,Oliveira-Campos, Ana M.F.,Samat, Andre,Guglielmetti, Robert

, p. 570 - 578 (2003)

The synthesis and the photochromic properties of new photochromic 6,7- and 7,8-benzoindene annellated benzopyrans are described. When compared to parent indeno-fused 2H-chromenes (2H-[1]benzopyrans), compounds 10 and 12 exhibit a significant bathochromic shift of maximum-absorption wavelength, an increase in the colorability, and similar fading rates.
