Abstract
a gradual lamellar curling-to-scrolling process. The supramolecular CDP-DA nanotubes are transformed into the rigid covalently cross-linked blue-phase polydiacetylene (CDP-PDA) by UV irradiation. Very interestingly, the blue-phase nanotubes display reversible thermochromic changing temperature up to 150 °C with excellent repeatability over a dozen thermal cycles. This work provides an efficient strategy for precise morphological control and aiding the perspective for development in nanostructures for functional devices.
