A novel photoactivated artificial muscle model unit is reported. Here we show that organic/inorganic hybrid nanosheets reversibly slide horizontally on a giant scale and the interlayer spaces in layered structure shrink expand vertically by photoirradiation. The sliding movement of system first example an having much similarity with natural fibrils. In particular, our molecular exhibits macroscopic morphological change (∼1500 nm) relative to size ∼1 nm means reversible mechanism.
