The concept of molecular switching within a cyclic four-stage process is introduced on the basis of two structurally fused photochromic systems (A-D). The synthesis of 1,8a-dihydro-2,3-bis(2,5-dimethyl-3-thienyl)azulene-1,1-dicarbonitrile (open/closed A) is described; irradiation with UV light leads to an equilibrium of open/open B, open/closed A and closed/closed C, whereas B is thermally rearranged to A by ring closure of the vinylheptafulvene substructure.
