photoactive molecules. Furthermore, this photochemical transition could be magnified by the supramolecular cooperative motions into a nanoscale motion of the
LCBCs. 2D and 3D photomechanical motions of LC elastomers and LCP composites are induced by light irradiation, which directly transfers light energy into
mechanical energy. In SLCP systems, microparticles and nanofibers are fabricated
by noncovalent interactions; besides, as an infant noncovalent interaction, halogenbonded LCs may have quite huge space for research. All these properties of
photoresponsive LCPs indicate their possible applications in energy conversion,
optical devices, nanotechnology and biomaterials.
