“…Together, these interactions prevented crystallization and induced the directional growth of a twisted superstructure (Figure a). Interestingly, they also found that odd or even numbers of carbon atoms led to opposite chiral superstructures, with right‐handed supramolecular structures produced with even‐numbered carbon chains and left‐handed supramolecular structures with odd‐numbered ones . This is because the different alkyl chain length produced a geometric difference in alignment to maximize the van der Waals interactions (Figure b).…”

The last decade has witnessed rapid developments in aggregation‐induced emission (AIE). In contrast to traditional aggregation, which causes luminescence quenching (ACQ), AIE is a reverse phenomenon that allows robust luminescence to be retained in aggregated and solid states. This makes it possible to fabricate various highly efficient luminescent materials, which opens new paradigms in a number of fields, such as imaging, sensing, medical therapy, light harvesting, light‐emitting devices, and organic electronic devices. Of the various important features of AIE molecules, their self‐assembly behavior is very attractive because the formation of a well‐defined emissive nanostructure may lead to advanced applications in diverse fields. However, due to the nonplanar topology of AIEgens, it is not easy for them to self‐assemble into well‐defined structures. To date, some strategies have been proposed to achieve the self‐assembly of AIEgens. Herein, we summarize the most recent approaches for the self‐assembly of AIE molecules. These approaches can be sorted into two classes: 1) covalent molecular design and 2) noncovalent supramolecular interactions. We hope this will inspire more excellent work in the field of AIE.

“…We demonstrate that the combination of achiral tetraphenylethene, an aggregation‐induced emission (AIE)‐active luminophore, bearing four even‐ or odd‐long alkyl chains via amide linkages in the molecular structure, allows the entire process of induction and control of supramolecular chirality into well‐defined helical superstructures by solvophobic control . TEM and SEM images confirm that these twisted ribbons are indeed formed by right‐ and left‐handed helices with an even or odd number of carbon in the alkyl chains, respectively.…”

Sheshanath V. Bhosale received his PhD from Freie University Berlin (Germany) in supramolecular chemistry under the supervision of Prof. J. H. Fuhrhop in 2004. He then pursued his postdoctoral studies with Prof. S. Matile at University of Geneva (Switzerland) under the auspices of a Roche Foundation Fellowship. This was followed by a stay at Monash University (Australia) for 5 years as an ARC‐APD Fellow. He worked at RMIT University, Melbourne (Australia) for 6 years as ARC‐Future Fellowship. Currently, Prof. Bhosale is working at the Department of Chemistry, Goa University (India) as a UGC‐FRP Professor, His research interests lie in the design and synthesis of π‐functional materials, especially small molecules, for sensing, biomaterials, and supramolecular chemistry applications. So far, Prof. Bhosale has produced 185 research articles and his work has been cited more than 4400 times, giving him an h‐index of 32. He currently serves as an active Editorial Board member for ChemistryOpen.

“…This inspiringd iscovery can alleviate the notorious ACQ effect of emitters, paving an alternative route for preparing efficient fluorescento rganic materials in the solid state. In addition to silole, many other organic compounds with AIE characteristics have been developed so far,s uch as tetraphenylethene (TPE) [6][7][8][9][10][11][12][13] and aryl-substituted pyrroles. [14][15][16][17] Luminogens with AIE features have been defined as AIEgens by Tang.…”

Organic functional materials, including conjugated molecules and fluorescent dyes, have been intensely developed in recent years because they can be applied in many fields, such as solar cells, biosensing and bioimaging, and medical adjuvant therapy. Organic functional materials with aggregation-induced emission or aggregation-enhanced emission (AIE/AEE) characteristics have increasingly attracted attention due to their high quantum efficiency in the aggregated or solid state. A large variety of AIE/AEE materials have been designed and applied during the exponential growth of research interest in the abovementioned fields. Multiphenyl-substituted 1,3-butadiene (MPB), as a core structure that includes tetraphenyl-1,3-butadiene, hexaphenyl-1,3-butadiene and their derivatives, show a typical AIE/AEE feature and can be potentially used in all the above-mentioned fields. This review summarizes the design principles, the corresponding syntheses, and the structure-property relationships of MPBs, as well as their excellent innovative functionalities and applications. This review will be useful for scientists conducting chemistry, materials, and biomedical research in AIE/AEE-related fields.
