Abstract
Dihydroazulene(DHA)/vinylheptafulvene(VHF) equilibration is based on photoc hemical ring opening and thermal cyclization. Optical and non-linear optica l properties of DHA/VHF are reported. Multimode switching, comprising both photo-redox and off/on-fluorescence switching, are investigated. DHA covale ntly attached to cellulose shows multifold switching. A concept for cyclic multistate switching is proposed based on biphotochromic compounds.
