“…[9] The term aggregation-induced emission (AIE), [3a,10] which is typically used for this phenomenon, has attracted interest in the past two decades, but is somewhat misleading, since not only aggregates show an emission "on" behaviour, but also a single molecule, when sterically entrapped in a demanding environment, such as a gel [11] or viscous solution, [12] a protein pocket [13] or a polymer. [14] These compounds typically featuring phenyl-rotors, have been used to fabricate reporter molecules for bioimaging, [15] luminescent polymeric materials [16] as well as organic light emitting diodes. [17] In between these two phenomena, a rational design concept combining both emissive properties appeared improbable since the molecular aspects of rigid planar structures (ACQ) and twisted movable moieties (AIE) seemed contradictive.…”

In this contribution, we describe a set of three chlorinated bridged ethers with varying numbers of sulfur and oxygen atoms. The substitution leads to highly emissive compounds with tunable photophysical properties in relationship to their state of aggregation, i. e. in solution, as aggregates and in the solid state. Additionally, an in-depth X-ray diffractometric analysis supported by a Hirshfeld study of non-covalent interactions and quantum chemical simulations was carried out. As the outcome, it was found that the content of sulfur in the compounds regulates the tuning of emission in solution as well as in the aggregated states as a consequence of their variation of planarity.

“…[69] Since then, AIE materials have aroused myriad interest for their potential applications in various fields. [70][71][72][73][74] Thus, polymers possessing AIE properties are considered to be ideal candidates for constructing CPL materials with both high g lum and large quantum yield (Φ) in the condensed phase. [75][76][77][78] Tetraphenylethene (TPE), as a typical AIE building block, has been widely used to construct CPL materials.…”

Chiral materials capable of generating circularly polarized luminescence (CPL) have gained rapidly growing research interest by virtue of their peculiar photophysical characteristics and far‐reaching applications. Amongst various CPL materials, polymer‐based CPL materials have constituted an important class owing to their abundant types, ease of manufacture, high thermal stability, as well as, tunable properties. The present work reviews the latest advances in constructing polymer‐based CPL materials, which are classified based on the interaction modes between chiral and luminescent components, that is, covalent interaction, non‐covalent interaction, as well as, without covalent and non‐covalent interactions. The newly emerging categories of polymer‐based CPL materials, that is, nonconventional fluorescence‐based CPL materials, circularly polarized room temperature phosphorescence, and polymer‐based CPL materials with thermally activated delayed fluorescence properties are also presented. Typical applications of the polymer‐based CPL emitters in organic light‐emitting diodes, information security encryption, and optical sensors are further discussed. Additionally, the current challenges and future perspectives in this field are summarized. This review article is expected to stimulate more unprecedented achievements derived from polymer‐based CPL materials, thus further promoting their future practical applications.

The discovery of aggregation-induced emission (AIE) phenomenon in 2001 has had a significant impact on materials development across different research disciplines. AIE-active materials have been widely exploited for various applications in optoelectronics, sensing, biomedical, and stimuli-responsive systems, etc. This is made possible by integrating AIE features with other fields of science and engineering, such as nanoscience and nanotechnology. AIE has been extensively employed, particularly for biomedical applications, such as biosensing, bioimaging, and theranostics. However, development of AIE-based nanotechnology for other applications is comparatively less, although there have been increasing research activities in recent years. Given the significance and potential of the marriage between AIE hallmark and nanotechnology in AIE-active materials development, this review article summarizes and showcases the latest research efforts in AIE-based nanomaterials, including nanomaterials synthesis and their nonbiomedical applications, such as sensing, optoelectronics, functional coatings, and stimuli-responsive systems. A perspective on the outlook of AIE-based nanostructured materials and relevant nanotechnology for nonbiomedical applications will be provided, giving an insight into how to design AIE-active nanostructures as well as their applications beyond the biomedical domain.
