Switching behavior of molecular nanotubes forming an inclusion complex with block copolymers in solutions is theoretically investigated. As temperature changes, a nanotube including a miscible block copolymer gradually moves from one polymer chain to the other, while a switching transition sharply occurs with a hysteresis loop in an immiscible block copolymer. In a recurrent block copolymer comprising linear polymers of four different types, a nanotube travels on the copolymer rail stepwise with undulating temperature: a molecular motor operated by temperature undulation.
