(a) Predicted in-plane shear deformation induced by UV irradiation. Corner angle and cyclization conversion ratio of lozenge-shaped single crystal are indicated in insets. (sample: 1,2-bis(2-ethyl-5-phenyl-3-thienyl)perfluorocyclopenetene single crystal, thickness: 0.57 μm, light wavelength: 350.58 nm, light intensity: 10–100 mW/cm2) (b) Experimental comparison (red triangular point: Kobatake et al.’s report4) with our model at 60 mW/cm2 of UV irradiation.
