Fluorescent Actuator Based on Microporous Conjugated Polymer with Intramolecular Stack Structure



original image

Fluorescent bilayer film, consisting of an active layer of a microporous conjugated polymer with intramolecular stack structure, is successfully fabricated. This bilayer film shows the simultaneous occurrence in actuation and fluorescence change in response to external chemical stimuli. Highly reversible uncurling-curling movement, accompanied with changes in fluorescence color and intensity, is achieved upon sequential exposure to alcohol and water.
