Abstract

Abstract : Organic crystal microwires that transform light into oscillatory motion are reported by Rabih O. Al‐Kaysi, Christopher J. Bardeen, and co‐workers in their Research Article on page 2414 . A diolefinanthracene derivative undergoes E – Z photoisomerization to generate molecular‐scale motion. When microwires composed of this molecule are exposed to UV and visible wavelengths, forward and reverse reactions drive continuous twisting and writhing. These motions can propel the wires at speeds controlled by the light intensity.
