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.

Keywords: isoindolinone; molecular devices; multi-stable switch; photochemistry; propeller.
