Abstract
This report demonstrates a novel strategy for the light-guided motion of a liquid droplet on photoresponsive surfaces based on reversible changes in surface free energy induced by light. When a liquid droplet in a mm-scale was placed on a substrate surface modified with a calix[4]resorcinarene derivative having photochromic azobenzene units, photoirradiation caused a gradient in surface free energy due to the photoisomerization of surface azobenzenes, leading to directional motion of the liquid droplet. This motion is ascribed to a force imbalance between two opposite edges of the liquid droplet induced by light.
