Recent Advances and Future Prospects of Aggregation‐induced Emission Carbohydrate Polymers

Abstract

Aggregation-induced emission (AIE) is an abnormal phenomenon that has sparked great attention for diverse applications in different fields. In particular, the fabrication and biological imaging applications of AIE-active fluorescent organic nanoparticles (FONs) have become a focus in the emerging and promising fields. A large number of AIE-active polymeric nanoprobes have recently been fabricated through different strategies. The advances and progress in this direction have also recently been summarized by some groups. However, the fabrication and biomedical applications of AIE-active FONs based on carbohydrate polymers and AIE-active dyes are quite rare and limited. In this feature article, the recently reported AIE-active FONs with different structures and applications based on AIE-active dyes and carbohydrate polymers are highlighted, and the major current limitations and development tendencies are also discussed.

Nano‐Star‐Shaped Polymers for Drug Delivery Applications

“…Here, the star polymer existed in the glassy state, resulting in reduced DNA transfection as compared to when rubbery polymers were utilized . Traditional methods of polymeric drug delivery simply encapsulates drugs to the hydrophobic cores, but this is often plagued by problems of early release or poor delivery as the micelles may start to degrade and unload the drugs before reaching their targets . This method is also usually characterized by low drug loading capacities.…”

Molecular Design, Circularly Polarized Luminescence, and Helical Self‐Assembly of Chiral Aggregation‐Induced Emission Molecules

“…If more patterns of non‐covalent interactions are constructed by deliberately optimizing the chemical structures of AIE molecules, the self‐assembly process will move towards the desired direction and more judicious self‐assembly architectures will be fabricated with the AIEgens. Thanks to the enthusiastic efforts of scientists, various fluorescent supramolecular architectures, such as micelles, fibers, wires, rods, and ribbons have been constructed by the self‐assembly of AIEgens . Among them, helical micro/nanostructures have drawn much attention owing to their fascinating structures and unique emissive behaviors …”

Synthesis, characterization, aggregation-induced emission, solvatochromism and mechanochromism of fluorinated benzothiadiazole bonded to tetraphenylethenes

“…[6][7][8] Recently, the aggregation induced emission (AIE) characteristics of small molecules and polymers has been proposed. [9][10][11][12] Tetraphenylethene (TPE) [13][14][15] with its propellershaped structure is one of the most studied examples for aggregation induced emission characteristics. Very recently, the TPE based molecules have been synthesized and investigated by Misra et al [16][17][18] The rational molecular design of the TPE based molecules makes it potential uses in non-doped OLEDs with a good color contrast.…”
