摘要

Abstract

The great potential of liquid-crystalline block copolymers (LCBCs) containing photoresponsive mesogens toward novel applications in photonics and nanotechnology has been attracting increasing attention

due to the combination of the inherent property of microphase separation of block copolymers and the hierarchically-assembled structures of liquid-crystalline polymers (LCPs). The periodically ordered nanostructures in bulk film of LCBCs can be acquired by supramolecular cooperative motion

derived from the interaction between liquid-crystalline elastic deformation and microphase separation

which are able to improve physical properties of polymer film toward advanced functional applications. Moreover

various micro/nano-patterned structures have been fabricated

via

light manipulation of photoresponsive LCBCs with good reproducibility and mass production. Thanks to recent developments in synthesis and polymerization techniques

diverse azobenzene-containing LCBCs have been designed

resulting in the creation of a wide variety of novel functions. This review illustrates recent progresses in macroscopic regulation of hierarchical nanostructures in LCBCs towards functional materials. The existing challenges are also discussed

showing perspectives for future studies.
