“…They used both analytic and numerical approaches and focused on the competition between the extrinsic bending energy and two‐dimensional Frank free energy 48 . Recently, they reported that the smectic LC ordering in the membrane of elongated ellipsoidal or tubular polymersomes was preserved when a tetraphenylethene providing aggregation‐induced emission (AIE) fluorescence was situated between hydrophilic and hydrophobic LC blocks 49 . The performance of these LC polymersomes and cholesterol‐based NPs could be regulated by other AIEgens which can be excited by light with wavelengths longer than those of UV, and thus the NPs of LC BCPs can be designed as fluorescent carriers of drugs in the future.…”

Anisotropic polymeric nanoparticles (NPs) have attracted considerable attention due to their morphology-dependent applications in the fields of nanocatalysts, drug delivery and sensors. By introducing liquid crystalline (LC) driving force into NPs, the region of non-spherical shapes in phase diagrams can be broadened effectively, which attracts great interest of many researchers. LC mesogens can be easily introduced to monomers, such as acrylates and methacrylates, as side groups connected by spacers with tunable length, and then side-chain LC polymers can be acquired after polymerization accordingly. Among these polymers, amphiphilic block copolymers (BCPs) have been widely studied, attributed to their property of spontaneous assembly into NPs under appropriate conditions. In this review, based on traditional solution self-assembly and polymerization-induced self-assembly, the recent research into side-chain LC BCP NPs is elaborated in terms of the aspects of the types of LC mesogens, LC phases, morphologies and functionalities. Finally, we summarize recent progress, and prospect the development trend in the future.

Steroid-based liquid crystal polymers and co-polymers have come a long way, with new and significant advances being made every year. This paper reviews some of the recent key developments in steroid-based liquid crystal polymers and co-polymers. It covers the structure–property relationship between cholesterol and sterol-based compounds and their corresponding polymers, and the influence of chemical structure and synthesis conditions on the liquid crystalline behaviour. An overview of the nature of self-assembly of these materials in solvents and through polymerisation is given. The role of liquid crystalline properties in the applications of these materials, in the creation of nano-objects, drug delivery and biomedicine and photonic and electronic devices, is discussed.

“…[3] Due to the stimuli-responsiveness, anisotropy and physiological medicine properties of LC NPs, they have received extensive attention in the fields of drug delivery, [4] functional nanomaterials [5] and so on. For example, Li et al [6] developed an LC nanoparticle with aggregation-induced emission (AIE) fluorescence group and cholesterol mesogen, which has the potential as imaging agents and drug carriers. Kasi et al [7] developed a brush gold LC nanoparticle containing the cholesterol mesogen, which successfully encapsulated the hydrophobic anticancer drug doxorubicin.…”

Liquid crystalline nanoparticles (LC NPs) are a kind of polymer NPs with LC mesogens, which can form special anisotropic morphologies due to the influence of LC ordering. Owing to the stimuli‐responsiveness of the LC blocks, LC NPs show abundant morphology evolution behaviors in response to external regulation. LC NPs have great application potential in nano‐devices, drug delivery, special fibers and other fields. Polymerization‐induced self‐assembly (PISA) method can synthesize LC NPs at high solid content, reducing the harsh demand for reaction solvent of the LC monomers, being a better choice for large‐scale production. In this review, we introduced recent research progress of PISA‐LC NPs by dividing them into several parts according to the LC mesogen, and discussed the improvement of experimental conditions and the potential application of these polymers.
