摘要：

Photochromic chromenes containing different spiro-carbocyclic moieties have been synthesized. A new pathway was developped to synthesize the required alpha,beta-ethylenic aldehydes precursors. On the other hand, two complementary procedures of ''chromenisation'' were successfully used. A study of the photochromic behavior allowed us to evaluate the influence of structural modifications: strong parameters variations were actually observed.
