Bichromophoric compounds containing the dihydroazulene ⇄ vinyl heptafulvene couple (see figure) with arenoid “R” groups which act as electron‐transfer groups can be triggered by visible light to produce an electric current. They are therefore of use as molecular switches. A number of different arenoid substituent have been employed and the compounds examined.
