Syntheses of Photochromic Molecules Based on a 1,5-Electrocyclic Reaction

SYNTHESES OF PHOTOCHROMIC MOLECULES BASED ON A 1,5-ELECTROCYCLIC REACTION 

Viewing photochromic systems on the basis of a 1,5-electrocyclization and its reverse, molecules must be envisaged in which the open ring as well as the cyclic structure have a similar energy content. This is the challenge in synthesizing molecules with tailor-made photochromic properties in connection with easy access to these molecules.
