Abstract

original image

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 (see scheme).
