Abstract

Phototaxis of azobenzene crystals is demonstrated for the first time by using a simple setup. The crystals on a glass move away from the light source like living organisms during visible light irradiation. The motion is driven by repeated melting and recrystallization associated with trans ↔ cis isomerization.
