The dihydroazulene (DHA)/vinylheptafulvene (VHF) photo/thermoswitch has been of interest for use in molecular electronics and advanced materials. The switching between the two isomers has previously been found to depend strongly on the presence of donor a
Light-Sensitive Dihydroazulenes: Alternative Synthesis - The Influence of Alkyl Substituents at the Five-Memeered Ring on the Photochromic Behaviour
Gierisch, Sebastian,Daub, Joerg
, p. 69 - 76 (2007/10/02)
Starting from cycloheptatrienylium tetrafluoroborate (8) the dihydroazulenes 1 were synthesized via substituted cycloheptatrienes 10 - 13 as intermediates.The dicyanovinyl derivatives 12 and 13 were transformed into vinylheptafulvenes 2 by dehydrogenation
