“…[ 28 ] CB[n]s (especially when n = 8) can form 1:2 host−guest complexes with monocationic guests, [ 29 ] and sometimes even the AIEgens can be included into their cavities and be put into the packing arrangements. [ 30 ] Benefitting from this fundamental knowledge, AIE‐active host−guest–driven supramolecular assemblies with promoted functionalities have been constructed for various real‐world applications. Because of the enhanced fluorescence properties of AIE systems and responsive features of host−guest–driven complexes, AIE‐active supramolecular assemblies with good water dispersity and biocompatibility are considered ideal materials for biomedical applications.…”

Aggregation‐induced emission (AIE), as an exciting photophysical phenomenon, has been regarded as one frontier research topic within both ranges of molecular luminescence and materials science over the last two decades. Since controllable molecular ensembles with particular morphologies and tunable functions can be elegantly constructed in the realm of supramolecular chemistry, the integration of supramolecular assembly and AIE systems can expectedly bring about luminescent materials with tunable emission and tailorable well‐ordered architectures. In this review, we will provide a summary of the creation and working mechanisms of AIE systems involving supramolecular systems that are driven by different supramolecular driving forces including hydrogen bonding, host−guest interactions, metal coordination, and π–π interactions. The morphological and photoluminescent features of these AIE‐active supramolecular assemblies will be elucidated, and the regulated fluorescence properties of the AIEgens induced by the assembling–disassembling processes will be discussed in detail.

“…The same group later reported an elegant example of light harvesting supramolecular block copolymers, [32] employing three other cyanostilbene derivatives 8 , 9 and 10 . Compounds 8 , 9 and 10 were also very weakly emissive in aqueous media as 7 and formed supramolecular homopolymers ( SHP s) in the presence of CB[8] exhibiting blue (480 nm), yellow (522 nm) and red (630 nm) emissions, respectively (Figure 8a) with moderate to high quantum yields ( 8 ‐ CB[8] : 27%, 9 ‐ CB[8] : 52% and 10 ‐ CB[8] : 8%).…”

Cucurbit[n]urils, the pumpkin shaped macrocyclic host molecules possessing a hydrophobic cavity and two identical carbonyl portals, have drawn a lot of attention in recent years due to their high‐affinity yet dynamic molecular recognition properties in water. The reversible and stimuli‐responsive nature of their host‐guest complexes imparts “smart” features leading to materials with intriguing optical, mechanical and morphological properties. In this review, we focus on the design of cucurbituril based luminescent materials in aqueous media as well in solid or film state. The design principles of fluorescent complexes, small assemblies as well as supramolecular polymers along with their stimuli‐responsive properties and applications in diverse areas such as optoelectronic devices, light harvesting, anti‐counterfeiting and information technology, cell imaging, etc are highlighted with selected examples from recent literature. We also discuss examples of room temperature phosphorescent materials derived from purely organic luminogens in the presence of cucurbiturils.

“…Recently, hyperbranched polymers, possessing 2D or 3D topological structures, have been demonstrated to effectively modulate the physical, chemical and even biological properties [8] . The highly branching characteristic of hyperbranched polymers make them unique among linear polymers, which have been investigated in many areas, such as self‐healing materials, [8d] drug delivery systems, [8e] light harvesting systems, [8f] sensing materials, [8g] and waste water treatment etc [8h] . Hyperbranched polymers have also been investigated in organic electronics, such as light‐emitting materials, [9] organic solar cells [10–11] as well as OFETs [12] .…”

Conjugated polymers with high charge mobilities have drawn increasing attention in organic field-effect transistors (OFETs) in recent years. However, OFETs of conjugated polymers with high mobility and good device stability remain a challenge. In this article, we report a hyperbranched polymer approach to improve the charge mobility and device stability. Three hyperbranched diketopyrrolopyrrole-based polymers were designed and synthesized via linear alkyl side-chain linkers. The results show that 2D topological hyperbranched polymers form stable thin film microstructures, and thus improve the device stability, since the conjugated moiety is interconnected by linear alkyl chain. Besides, the incorporation of linear alkyl chain instead of branching alkyl one reduce steric hindrance, and improve the microstructure ordering as well as the charge mobility. Barcoated OFETs result demonstrates that the devices mobilities and operational stabilities (bias stability and bending resistance) are both improved. All these indicate that hyperbranched polymer is a potential candidate for future application.
