Abstract:
Switched on! A tetra-stable switch has been synthesized in two steps, utilizing photoresponsive isoindolinone moieties. Sequential E-Z isomerization induced by 365 nm light results in a propeller switching action that is reversible using 458 nm light, acid, and high temperature.

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
